Continuous variation describes characteristics that can change over a range of values. Height is an example of continuous variation. Examples of continuous variation can be affected by both environmental and inherited factors.

Discontinuous variation describe characteristics that can be one of a limited number of options. Eye colour is an example of discontinuous variation. Examples of discontinuous variation are inherited.

We are going to record data on the different eye colours in the class. Eye colour is an example of discontinuous variation. When the data you record has set categories, we display this using a bar chart.
