Data Types
1. The problem asks to identify types of data: qualitative vs quantitative, discrete vs continuous.
2. Qualitative data describes qualities or categories (non-numeric), while quantitative data involves numbers and measurements.
3. Discrete data can only take specific values (often counts), continuous data can take any value within a range (measurements).
4. Examples:
- Qualitative data: "The colour of a car" (a category, not numeric).
- Quantitative data: "The mass of an apple" (a numeric measurement).
- Discrete data: "The number of people who read a blog" (countable whole numbers).
- Continuous data: "The mass of an orange" or "The distance a person travels" (measurable with decimals).
5. For Akhilla's table:
- Volume of water drunk in a day (L) is continuous data because it can take any decimal value.
- Number of snacks eaten in a day is discrete data because it counts whole snacks.
Final answers:
- Qualitative example: The colour of a car.
- Quantitative example: The mass of an apple.
- Discrete example: The number of people who read a blog.
- Continuous examples: The mass of an orange, The distance a person travels, Volume of water drunk in a day.
This explains how to classify data types clearly and with examples.
