Lesson details
Key learning points
- Some features have discontinuous variation (limited variations falling into particular categories).
- Some features have continuous variation (can take any value within a range).
- Examples of features in humans, other animals and plants that show discontinuous and continuous variation.
- Collecting primary data on examples of discontinuous and continuous variation in features.
Keywords
Discontinuous variation - Variation that is categorical (divided into particular categories).
Continuous variation - Variation that can take any one of many values over a continuous range.
Value - A number generated by a measurement, such as a measurement of mass or length.
Common misconception
All types of variation can be measured in the same way.
The lesson explores the differences between discontinuous and continuous variation and how they can be measured.
