Variation: PCA

Variation: PCA:


When measuring variation in certain characteristics there are a range of values with some values more common then others. E.g. Human
adult height ranges from 87cm-246.5cm BUT most are 150-190cm.

Range in human height is caused by both inherited and environmental variation. This is an example of continuous variation. This means the values can be any number within a certain range.

Shoe size is Discontinuous variation. Which means they only have a fixed set of values.
