Question

With respect to numerical and categorical data, choose the correct following options.

• A. The data in which every value collected is a number is known as numerical data.
• B. The set of numerical information that can be categorised into different groups forms a part of categorical data.
• C.
  This data is an example of numerical data.
• D.
  This forms an example of categorical data.

Answer 1

Answer: (A), (C), (D)

This forms an example of categorical data.
If in a data set every value is a number, then the data set is said to be a part of numerical data.

On the other hand, the set of non-numerical information that can be categorised into different groups is known as categorical data.

Observe the given data,


Since every value is a number, therefore this is an example of numerical data.

Now, observe the other given example.


Here, the information collected is non-numerical and thus can be categorised into different groups, thus this is an example of categorical data.

Hence, first, third, and fourth given options are correct.
