Question

Which of the following are examples of categorical data?

• A. The data depicting the age of $6$ students of a class.
• B. The hair colour of a group of $5$ people.
• C. The destinations selected by $7$ students for annual outing.
• D. The number of tourists visiting the museum on different days of a week.

Answer 1

Answer: (B), (C)

The destinations selected by $7$ students for annual outing.

The non-numerical information which can be categorised into different groups comes under categorical data.

For example, the hair colour of $5$ people can be represented as:


The different destinations selected by $7$ students for annual outing can be represented as:


As both the above data divides the information into different groups, i.e., hair colour and destination selected, thus both these are the examples of categorical data.

On the other hand, the data in which every value is a number constitutes numerical data.

For example, the data depicting the age of $6$ students of a class can be represented as:


The number of tourists visiting the museum on different days of a week can be represented as:


Since both these information are depicted using numerical values, therefore these data sets fall under numerical data and not categorical data.
