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).
