Discrete and Continuous Variables - Class XII

Size of a shoe can have integer values only. Hence, it is a discrete variable.

Size of shoe can have have only integer value. Hence, it is a discrete variable.

A discrete variable is a variable whose value is obtained by counting.
So, are you a girl or boy is an example of discrete variable.
Since it is answerable.

Discrete variables are countable in a finite amount of time.
So, number of heads when flipping a coin is a discrete variable statement because once the coin is flipped, we will get head or tail result.

Discrete variables are countable in a finite amount of time.
So, number of heads when flipping a coin is a discrete variable statement because once the coin is flipped, we will get head or tail result.

Discrete variables are countable in a finite amount of time.
Example: Count the number of people in your home.

A discrete variable is a variable whose value is obtained by counting.
So, how many times will you brush your teeth is countable.

Weight of a dog is not a discrete variable.
Because, the weight of a dog is a continuous variable as it can take any value - for example, $2$ kg, $5$ kg, $4.2$ kg etc.

A discrete variable is a variable whose value is obtained by counting.
So, here the student can able to say how many times he visited the doctor.
Therefore, the given statement is discrete.

Discrete variables are countable in a finite amount of time.
So, counting a number of students in a class is an example of discrete variable.
Because we can easily count the number of students in a class.

Discrete variables are countable in a finite amount of time.
So, number of chocolates in a box is an example of discrete variable.
Because we can easily count the number of chocolate in a box.

A discrete variable is a variable whose value is obtained by counting.
So, discrete variables measured with enough precision can often be considered continuous for practical purposes.
Example: number of students absent in a class.

Continuous variable has the infinite set of the data.
Example: Time taken to write a homework.

A continuous variable is a variable whose value is obtained by measuring.
So, the length of someone's foot is an example of continuous variable.

Continuous variable has the infinite set of the data.
So, are you a girl or boy is not an example of continuous variable.

A continuous variable is a variable whose value is obtained by measuring.
So, The weight of students in a class is an example of continuous variable.

A discrete variable is a variable whose value is obtained by counting.
So, height of animals in a park is not a discrete variable. 
Because the height will not be same for all animal, it may varying in height. 
example: elephant - $4$ m, tiger - $2$ m, giraffe - $10$ m

A discrete variable is a variable whose value is obtained by counting.
So, number of bubbles in a fish tank is countable.

A continuous variable is a variable whose value is obtained by measuring.
Example: The weight of a cat is a continuous variable as it can take any value - for example, $2$ kg, $4$ kg, $3.2$ kg etc.

A continuous variable is a variable whose value is obtained by measuring.
So, distance travelled from classes is an example of continuous variable.

A continuous variable is a variable whose value is obtained by measuring.
The height of animals in park is a continuous variable.
Because the animals have different heights.

Continuous variable has the infinite set of the data.
So, weight of a newborn is an example of continuous variable.
Because the weight may vary from $2.3$ kg, $3.1$ kg, $4$ kg etc.

Continuous variable has the infinite set of the data.
So, time taken to complete a task is an example of continuous variable.
For example time taken to complete a task will be $1$ minute $10$ seconds, $1$ minute $20$ seconds, and so on.

Continuous variable has the infinite set of the data.
Example: height of students in a class
Each and every students in a class has different heights, like $56.5, 45.9, 67.8$ etc..

A continuous variable is a variable whose value is obtained by measuring.
So, time taken to complete a task is a continuous variable as it can take any value - for example, $2$ hours $2$ mins, $2$ hours $20$ seconds etc..

A continuous variable is a variable whose value is obtained by measuring.
Example: 
The weight of a cat is a continuous variable as it can take any value - for example, $3.4$ kg, $3.5$ kg, $4.01$ kg, etc.

Continuous variable has the infinite set of the data.
So, weight of a cow is a continuous variable.
Since the weight can be measured in $3.5$ kg, $12.05$ kg, $12.5$ kg, $37.9$ kg etc..

A continuous variable is a variable whose value is obtained by measuring.
So, weight of animals in zoo is a continuous variable as it can take any value - for example, $3$ kg, $3.567$ kg, $4.01$ kg, etc.

A continuous variable is a variable whose value is obtained by measuring.
So, distance, height and length are continuous variable.
Therefore, number of cars in a  street is not a continuous variable.

There are two types of variables. Discrete and continuous.
