Qualitative data:

Qualitative variable categories each individual to corresponding groups. It is used for classification of individuals based on some attributes or qualities or characteristics. Categorical variable is also called as qualitative variable or nominal variable. In other words, it can be said that, a variable that is used for classification of individuals based on some attributes or qualities or characteristics are called categorical or qualitative variable.

Qualitative data are non-numerical measures such as characteristics, attributes or labels.

Step 2

Quantitative data:

A variable that provides numerical values of individual and Arithmetic operations such as addition and subtraction produce meaningful results are called quantitative variables. A quantitative data contains measured numerical values with measurement units.

Step 3

Here, the investigator asks the subjects about their age in years and age of the subjects is numerical value. Hence, the data corresponding to subjects their age in years is a quantitative data.
