## The Lesson

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").
• Colours ("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).
