Data can be Descriptive (like “high” or “fast”) or Numerical (numbers). And Numerical Data can be Discrete or Continuous: Discrete data is counted, Continuous data is measured.
Discrete Data can only take certain values. Example: the number of students in a class (you can’t have half a student).
Continuous Data can take any value (within a range) Examples:
- A person’s height: could be any value (within the range of human heights), not just certain fixed heights,
- Time in a race: you could even measure it to fractions of a second,
- A dog’s weight,
- The length of a leaf,
- Lots more!
