Difference Between Average and Mean

To understand the difference between average and mean, one must be aware of what separates one from the other. Average and mean are used interchangeably. In Statistics, instead of the term “average”, the term “mean” is used.

Difference Between Log and Ln

The difference between log and ln is that log is defined for base 10 and ln is denoted for base e. For example, log of base 2 is represented as log2 and log of base e, i.e. loge = ln (natural log).

Difference Between Mean and Median

 The difference between mean and median is explained in detail here. In statistics, mean is the average of a set of data and the median is the middle value of the arranged set of data.

Difference Between Variance and Standard Deviation

 Understanding the main difference between Variance and Standard deviation is important to know. These mathematical terms are usually used in normal mathematical equations to solve problems.

Difference Between Mutually Exclusive and Independent Events

The difference between mutually exclusive and independent events is: a mutually exclusive event can simply be defined as a situation when two events cannot occur at same time whereas independent event occurs when one event remains unaffected by the occurrence of the other event.

Difference Between Fraction and Rational Number

There is a massive difference between a fraction and a rational number. The concept of “fractional numbers” and “rational numbers” are closely related but are different in various aspects.

Difference between Relation and Function

The difference between relations and functions are a bit confusing as they both are closely related to each other.

Difference Between Natural and Whole numbers

The key difference between natural number and whole number is the presence of value ‘0’ in whole numbers. A number is an arithmetic value which is used to represent a particular quantity. The different types of numbers are classified based on their characteristic properties.

Difference between Parabola and Hyperbola

The major difference between parabola and hyperbola is based on their eccentricity. For parabola, eccentricity is equal to 1, and for hyperbola, eccentricity is greater than 1.

Difference between Length and Height

 Difference between length and height is very precise, as length denotes how long shape is and height denotes how tall it is. Length is the horizontal measurement in a plane whereas height is the vertical measurement.

Difference Between Rhombus and Parallelogram

 In Geometry, a quadrilateral is a four-sided polygon. The different quadrilaterals are square, rectangle, rhombus, parallelogram, kite, trapezium which have some similar characteristics. But these shapes are different from each other because of their few properties.

Difference between Area and Volume

The term Area and Volume can create considerable confusion in understanding the terms. Although they seem to be of like a similar quantity of measurement, in reality, they are very much different from each other.

Difference between Area and Perimeter

 The key difference between area and perimeter is: area is the region occupied by shape and perimeter defines the length of the outer boundary of the shape. Both the parameters define the size of a shape. Learn more on perimeter and area here.

Difference between Circle and Sphere

There are a few fundamental differences between a circle and sphere which separates them in a lot of ways. Both the circle and sphere are different, even if they are circular objects.

Difference between Rational & Irrational Numbers

The key difference between rational and irrational numbers is, the rational number is expressed in the form of p/q whereas it is not possible for irrational number (though both are real numbers).

Difference Between Square and Rectangle

The major difference between square and rectangle is that a square has all its sides equal whereas a rectangle has its opposite sides equal. All geometrical shapes can fall under any one of the categories such as two-dimensional shapes or three-dimensional shapes. All the shapes can share a few characteristics.

Difference Between Trigonometry and Geometry

PRE-REQUISITES FOR INSTALLING LARAVEL
Before installing Laravel, ensure that you have the following programs already installed 1. Web server 2. PHP 3. MySQL 4. Composer 5. Integrated Development Environment (IDE)

Web Server, PHP & MySQL

For this tutorial, we will use XAMPP. XAMPP comes with Apache, MySQL and PHP. The good news is XAMPP is cross platform.

Difference Between Mass and Matter

Mass and matter are two terms that we often hear about both in chemistry and physics classes. Besides, these are two important principles that science students need to understand very clearly and not get confused between them. Most of the time, because of their close relation and an assumption that they can be used interchangeably students tend to misplace the words.

Difference Between Oxidation and Reduction

The chemical reactions which often work together are oxidation and reduction. During this reaction there is an exchange of electrons. When reduction oxidation reactions occur simultaneously it is called as redox reaction or reduction- oxidation reaction.

Difference Between Sodium Carbonate and Sodium Bicarbonate

However, even though sodium carbonate and sodium bicarbonate sound similar in their names, these two substances are not the same and have many features and uses that are different.

Difference Between Atomic Weight and Atomic Mass

Atomic mass and atomic weight do not mean the same but still some people use the terms interchangeably. To make you understand how atomic mass and atomic weight are different from each other, some major differences between atomic mass and atomic weight mentioned below:

Difference Between Fluid and Liquid

It is also worth mentioning that liquids are fluids but not all fluids are liquids. It is mainly because fluids also comprise substances in a gaseous phase. To give you an example, Nitrogen gas is a fluid, whereas a mango juice is both a fluid and a liquid.

Difference Between Evaporation and Condensation

When we study liquids in chemistry, we tend to hear words like evaporation and condensation a lot. While these words tend to sound the same but there are totally different when it comes to the nature of the processes.

Difference Between Atom and ION

To make you understand how atom and ion are different from each other, here are the some major differences between atom and ion:

Difference Between Elements and Atoms

Before getting into the major differences, let’s have a look at what these terms mean. So, an element is basically a pure or raw chemical substance that consists of one or a certain type of atom. An element is categorized based on its atomic number. They have been classified and grouped as metal, metalloids and non-metals in the periodic table.

Difference Between Glucose and Fructose

Important carbohydrates required for the body are glucose, fructose, and sucrose. Glucose and fructose are simple sugars. Simple carbohydrates are classified into two types. They are monosaccharide and disaccharide.

Difference Between Alkali and Base

To make you understand how alkali and base are different from each other, here are some of the major differences between alkali and base:

Difference Between Cell and Battery

Thermosetting Plastics (Thermoplastic Vs Thermosetting Plastics)

Talking about the differences between thermoplastic and thermosetting plastic, well the main distinguishing factor between the two is that, thermoplastic materials typically have low melting points due to which they can further be remoulded or recycled easily.

Difference Between Vaporization and Evaporation

Differences between vaporization and evaporation are here to further understand that these two processes are not exactly the same. Usually, many people tend to be confused about these two processes and many a time these terms are misunderstood.

Difference Between Orbit and Orbitals

The difference between orbit and orbitals is important to understand in the field of chemistry. The important thing to understand is that they are different from one another. Even though they sound the same and it is quite possible for one to get confused with other, one should understand the key differences between one and the other.

Difference Between Reflection and Refraction

 The two phenomena based on straight light propagation are reflection and refraction, wherein the reflection deals with the bouncing of light rays whereas the refraction talks about bending of light rays.

Difference between Power And Energy

 People always seem to consider Energy and Power to be the same. They even make the mistake of thinking ‘Energy and Power’ as synonyms. It is not that difficult to distinguish between Energy and power.

Difference between Kinetic and Potential Energy

The capacity to do work is called as Energy. This energy can be stored in different forms. Energy is one of the physical quantities as it is proportional to the mass of the object. The ability of the body to exert a push or a pull against the natural forces like gravity identifies as to what kind of energy is it.

Difference Between Resistance and Resistivity

In difference Between Resistance and Resistivity, Resistance is defined as the property of the conductor which opposes the flow of electric current whereas Resistivity is defined as the resistance offered by the material per unit length for unit cross-section. Below the detailed comparison and differences between resistivity and resistance.

Difference Between Heat and Temperature

Heat and temperature in our daily life in terms of weather or sometimes in terms of temperature. But we know the difference between heat and temperature is important to realize the minute difference between heat and temperature scales of measuring hotness or coldness of any object.

Difference Between Watts and Volts

The difference between watts and volts are here in very simple and easy to understand. These differences between watts and volts will help to remember each point better and understand in-depth concepts effectively.

Difference Between Voltage And Current

The difference between voltage and current is one of the most commonly asked questions from the electricity topic of physics. The difference between volts and amps given here can help the students to understand the basics better and know their comparisons thoroughly.

Difference Between Mass and Weight

Difference between mass and weight is one of the most frequently asked questions. Some students often use the terms mass and weight interchangeably, which is completely wrong. It is important to know what they are and how they are related. 

Difference Between Concave and Convex Mirror

The difference between concave and convex mirror is crucial to understand as the properties of both these mirrors are not properly understood by most of us. The differences between concave and convex mirror are listed below in a tabular form to help students assimilate the concept efficiently.

Pakistan is land of variety, and so are her professions. Jugglers are a very common sight in Pakistan. They provide us amusement and fun. They are generally found in small towns, villages and at fairs. In a big cities like Lahore, we come across very few jugglers because there is not much open space where a juggler can give his performance. Besides, there is much hurry about every thing and a great rush of traffic. The police does not allow them to show their feats which may attract big crowds. People have so many other attractions and means of recreation that they show no interest in the antiquated tricks of the jugglers. The educated people in particular, can’t afford to waste their time over it.

Social Issues

Social issues are found in abundance in our country. Some of the common social issues which seem to have plagued the Indian society are child abuse, illiteracy, drug abuse, child trafficking, poverty, unemployment, gender disparity, and so on. It is really important for the nation to come together and take a stand against these problems.

If we do not do our bit right now, these social issues might become too huge for our country to function properly.

Causes and Effects of the Popularity of Fast Food

 The taste which only fulfils our tongue and no good to our health is always poisoning to us. Fast food is such a poison which is also known as slow poison. It gradually affects the inner parts of our life span. It is responsible for our mental agitation. Now the question is that why we the modern people are too much fond about such fast food.? 

There are so many causes of popularity such fast food restaurants. The first is obviously the needs of modern people who are very busy in their lifestyle. Mostly families have no time to cook and it is fashion to eat outside. Most of the people work the whole day without a lunch break. Thus, they are addicted physically and mentally with fast food. 

Memories of Eid-ul-Adha

Every year, the arrival of Eid-ul-Azha brings a wave of excitement in our homes. The enjoyment and contention we derive from feeding animals and taking care of them is just very special.

Watching animals that got attached with us, being sacrificed is emotional and scary at the same time. And the barbecue of the sacrificial meat that we do at night is an absolutely amazing time because all home fellows along with cousins gather as we cook and eat together. We play, laugh and enjoy lot of. 

The joy of this Eid is unmatchable, therefore let me share some of my memories from last Eid-ul-Azha celebration. Last year we bought a cow and a goat for us. They were both very beautiful, Masha Allah. I used to feed the goat with my own hands and my brother did the same with cow. Although, I am always a bit scared of animals, last time eid ul azha was different.

Becoming a Responsible Citizen: Can Education Help?

 Every citizen has duties and responsibilities which they have to fulfill in a suitable manner. 

Education builds the character of a citizen. Education doesn’t mean just to study course books but its actual meaning is to understand the lessons of the book. Education should not be considered complete until it is practiced. So besides studying and understanding, applying the lessons of books in our daily life is very important. 

Education is very important in making a responsible citizen. Education is helpful in many ways. An educated person knows about his responsibilities and rights well. 

Citizenship

 As Oprah Winfrey said “Education begins with gentleman, action complete him.”

A citizen is a person who is national of his country. Citizenship means “to work for the nation’s prosperity. It is said: 

“It doesn’t matter how small one is, one can still make a difference.”

That means we should not see that how small a person is but that his contribution can change the standard of education, health facilities and other aspects of society for a better future. 

Social and Cultural Diversity

 Diversity means the existence of different cultures, customs, beliefs, traditions and languages in a place or different places at a given point in time. Diversity resembles the mix of different ingredients with the masala (spices) in a mixed vegetable dish. If we take an example of a recipe, we will come to know about different ingredients of various flavors which are equally important in providing a collectively good taste: tomatoes, green and red chillies and salt, all combined would provide beauty, great taste, to the salad and would draw everyone towards it.

Adjective

adjective (noun): a part-of-speech that modifies or describes a noun or a pronoun
An adjective is one of the eight parts of speech.

An adjective is a word that tells us more about a noun. It "describes" or "modifies" a noun (The big dog was hungry). In these examples, the adjective is in bold and the noun that it modifies is in italics.

Pronouns

Pronouns are small words that take the place of a noun. Pronouns are words like: he, you, ours, themselves, some, each... We can use a pronoun instead of a noun. If we didn't have pronouns, we would have to repeat a whole lot of nouns. 

What is Pronoun?
Pronouns are small words that take the place of a noun. We can use a pronoun instead of a noun. Pronouns are words like: he, you, ours, themselves, some, each... If we didn't have pronouns, we would have to repeat a lot of nouns. We would have to say things like:
  • Do you like the manager? I don't like the manager. The manager's not friendly.
With pronouns, we can say:
  • Do you like the manager? I don't like him. He's not friendly.
A pronoun is a small word with a big job. In fact, a pronoun can take the place of an entire noun phrase. In this way, pronouns help us use fewer words and avoid repetition.

A pronoun represents the person or thing that we are talking about (as long as we know which person or thing we are talking about). We don't usually start a discourse with a pronoun. We start with a noun and then move on to use a pronoun to avoid repeating the noun.

By "noun", we really mean: noun (food), name (Tara), gerund (swimming), noun phrase (twelve red roses). We can replace even a long noun phrase such as "the car that we saw crashing into the bus" with the simple pronoun "it".

Pronoun Rules
Rule 1. Subject pronouns are used when the pronoun is the subject of the sentence. You can remember subject pronouns easily by filling in the blank subject space for a simple sentence.

Example: ___ did the job.
I, he, she, we, they, who, whoever, etc., all qualify and are, therefore, subject pronouns.

Rule 2. Subject pronouns are also used if they rename the subject. They will follow to be verbs, such as is, are, was, were, am, will be, had been, etc.

Examples:
It is he.
This is she speaking.
It is we who are responsible for the decision to downsize.

Rule 3. This rule surprises even language watchers: when who refers to a personal pronoun (I, you, he, she, we, they), it takes the verb that agrees with that pronoun.

Correct: It is I who am sorry. (I am)
Incorrect: It is I who is sorry.

Correct: It is you who are mistaken. (you are)
Incorrect: It is you who's mistaken.


Rule 4. In addition to subject pronouns, there are also object pronouns, known more specifically as direct object, indirect object, and object of a preposition. Object pronouns include me, him, herself, us, them, themselves.

Examples:
Jean saw him.
Him is the direct object of the verb saw.

Give her the book.
The direct object of give is book, and her is the indirect object. Indirect objects always have an implied to or for in front of them: Give [to] her the book. Do [for] me a favor.

Are you talking to me?
Me is the object of the preposition to.


Rule 5. The pronouns who, that, and which become singular or plural depending on the subject. If the subject is singular, use a singular verb. If it is plural, use a plural verb.

Example: He is the only one of those men who is always on time.
The word who refers to one. Therefore, use the singular verb is.

Sometimes we must look more closely to find a verb's true subject:

Example: He is one of those men who are always on time.
The word who refers to men. Therefore, use the plural verb are.

In sentences like this last example, many would mistakenly insist that one is the subject, requiring is always on time. But look at it this way: Of those men who are always on time, he is one.

Pronoun Case
Pronouns (and nouns) in English display "case" according to their function in the sentence. Their function can be:

subjective (they act as the subject)
objective (they act as the object)
possessive (they show possession of something else)

Types of Noun

Types of Nouns
Nouns are an important part of speech in English, probably second only to verbs. It is difficult to say much without using a noun.

There are several different types of English nouns. It is often useful to recognize what type a noun is because different types sometimes have different rules. This helps you to use them correctly.

Common Nouns and Proper Nouns
Common Nouns
Most nouns are common nouns. Common nouns refer to people, places and things in general like chair or dog. Any noun that is not a name is a common noun.

Examples: teacher, car, music, danger, receipt
  • Have you seen my dog?
  • The books are on your desk.
  • ...the pursuit of happiness.
Proper Nouns
Names of people, places or organizations are proper nouns. Your name is a proper noun. London is a proper noun. United Nations is a proper noun.

Rule: Proper nouns always start with a capital letter.

Examples: Jane, Thailand, Sunday, James Bond, Einstein, Superman, Game of Thrones, Shakespeare
  • Let me introduce you to Shayan.
  • The capital of Pakistan is Islamabad.
  • He is the chairman of the Pakistan Broadcasting Corporation.
  • I was born in August.
Note: Adjectives that we make from proper nouns also usually start with a capital letter, for example Shakespearian, Orwellian.

Concrete Nouns and Abstract Nouns
Concrete Nouns
Concrete nouns are physical things that you can touch.

Examples: man, rice, head, car, furniture, mobile phone
  • How many stars are there in the universe?
  • Have you met James Bond?
  • Pour the water down the drain.
Abstract Nouns
Abstract nouns are the opposite of concrete nouns. They are things that you cannot touch. Abstract nouns are ideas, concepts and feelings.

Examples: happiness, courage, danger, truth
  • He has great strength.
  • Who killed President Kennedy is a real mystery.
  • Sometimes it takes courage to tell the truth.
  • Their lives were full of sadness.

Countable Nouns and Uncountable Nouns
Countable Nouns
(also called count nouns)

You can count countable nouns. Countable nouns have singular and plural forms.

Examples:  ball, boy, cat, person
  • I have only five dollars.
  • The Earth was formed 4.6 billion years ago.
  • There are lots of people but we don't have a car.
Uncountable Nouns
(also called mass nouns)

You cannot count uncountable nouns. You need to use "measure words" to quantify them.

Rule: We never use uncountable nouns with the indefinite article (a/an). Uncountable nouns are always singular.

Examples: water, happiness, cheese
  • Have you got some money?
  • Air-conditioners use a lot of electricity.
  • Do you have any work for me to do?
  • Many Asians eat rice.
Collective Nouns
A collective noun denotes a group of individuals.

Examples: class (group of students), pride (group of lions), crew (group of sailors)

Rule: Collective nouns can be treated as singular or plural. More about this at rules of subject-verb agreement with collective nouns.
  • His family live in different countries.
  • An average family consists of four people.
  • The new company is the result of a merger.
  • The board of directors will meet tomorrow.
Compound Nouns
A compound noun is a noun that is made with two or more words. Most compound nouns are [noun + noun] or [adjective + noun]. Each compound noun acts as a single unit and can be modified by adjectives and other nouns.

Compound nouns have three different forms:
  • open or spaced - space between words (bus stop)
  • hyphenated - hyphen between words (mother-in-law)
  • closed or solid - no space or hyphen between words (football)
Examples: cat food, blackboard, breakfast, full moon, washing machine, software
  • Can we use the swimming pool?
  • They stop work at sunset.
  • Don't forget that check-out is at 12 noon.

What is a Noun?

What is a Noun?
noun (noun): a word (except a pronoun) that identifies a person, place or thing, or names one of them (proper noun)
The simple definition is: a person, place or thing. Here are some examples:
  • person: man, woman, teacher, John, Mary
  • place: home, office, town, countryside, America
  • thing: table, car, banana, money, music, love, dog, monkey
The problem with the simple definition above is that it does not explain why "love" is a noun but can also be a verb.
Another (more complicated) way of recognizing a noun is by its:
  • ending
  • position
  • function
1. Noun ending
There are certain word endings that show that a word is a noun, for example:
  • -ity → nationality
  • -ment → appointment
  • -ness → happiness
  • -ation → relation
  • -hood → childhood
But this is not true for the word endings of all nouns. For example, the noun "spoonful" ends in -ful, but the adjective "careful" also ends in -ful.

2. Position in sentence
We can often recognise a noun by its position in the sentence.

Nouns often come after a determiner (a determiner is a word like a, an, the, this, my, such):
  • a relief
  • an afternoon
  • the doctor
  • this word
  • my house
  • such stupidity
Nouns often come after one or more adjectives:
  • a great relief
  • a peaceful afternoon
  • the tall, Pakistani doctor
  • this difficult word
  • my brown and white house
  • such crass stupidity
3. Function in a sentence
Nouns have certain functions (jobs) in a sentence, for example:

subject of verb: Doctors work hard.
object of verb: He likes coffee.
subject and object of verb: Teachers teach students.

But the subject or object of a sentence is not always a noun. It could be a pronoun or a phrase. In the sentence "My doctor works hard", the noun is "doctor" but the subject is "My doctor".
