Types of Data
Types of Data
There are different types of data.
Qualitative and Quantitative Data
The main distinction is between qualitative (words) and quantitative (numbers) data.

Qualitative data is described in words. For example:

Names ("Steven", "Victoria", "Hema").

Colors ("Red", "Blue", "Yellow").

Gender ("Male", "Female").


Quantitative data is described in numbers. For example:

Ages (13, 31, 55).

Incomes (£25,000, $70,000, €45,750).

Lengths (155 cm, 6 feet, 15 inches).

Types of Quantitative Data: Discrete and Continuous
There are also two types of quantitative data: discrete and continuous data.

Discrete data can only take certain values, like whole numbers. Discrete data is counted. For example:

Ages (13, 31, 55).

Test scores (8, 10, 5).

Number of pets (0, 2, 4).


Continuous data can take any value (within a range). Continuous data is measured. For example:

Lengths (155 cm, 6 feet, 15 inches).

Times (5 seconds, 2¾ minutes, 1½ hours).

Lengths (155 cm, 6 feet, 15 inches).
