Numerical Data

Numerical data, also called quantitative data, is measurable data expressed using numbers. Some examples of numerical data are age, height, and weight of a person. Consider the following personal information.
Person Age Weight Shoe Size Number of Siblings Eye Color
Dejen Blue
Madge Green
Yulia Brown

A person's age, weight, shoe size, and number of siblings are examples of numerical data. In contrast, a person's eye color cannot be expressed in numbers and is an example of categorical data. Additionally, numerical data can be either discrete data that can only take specific values or continuous data that can take any value within an interval.

Data Numerical? Type
