The weight of students in a class is an example of ________ variable.

  1. discrete

  2. continuous

  3. dependent

  4. nominal


Correct Option: B
Explanation:

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.

The height of animals in park is not a _______ variable.

  1. discrete

  2. dependent

  3. nominal

  4. continuous


Correct Option: A
Explanation:

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

What type of variable is this?
Number of bubbles in a fish tank.

  1. dependent

  2. continuous

  3. nominal

  4. discrete


Correct Option: D
Explanation:

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

A _______ variable is a variable whose value is obtained by measuring.

  1. dependent

  2. continuous

  3. discrete

  4. nominal


Correct Option: B
Explanation:

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.

distance travelled from classes.

  1. discrete

  2. dependent

  3. nominal

  4. continuous


Correct Option: D
Explanation:

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

The height of animals in park is a _______ variable.

  1. discrete

  2. continuous

  3. nominal

  4. dependent


Correct Option: B
Explanation:

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.

Which one of the following is a continuous variable statement?

  1. how old are you?

  2. number of students in a class

  3. weight of a new born

  4. count the number of chocolates in a jar


Correct Option: C
Explanation:

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.

Time taken to complete a task. The answer is an example of which type of variable?

  1. discrete

  2. dependent

  3. continuous

  4. nominal


Correct Option: C
Explanation:

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 ______ set of the data.

  1. finite

  2. infinite

  3. composite

  4. definite


Correct Option: B
Explanation:

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..

Example of continuous variable is ________.

  1. number of bubbles in a fish tank

  2. time taken to complete a task

  3. are you a girl or boy?

  4. toss a coin to get head


Correct Option: B
Explanation:

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..
