Some differences, or variations, cover a whole range of things and are called continuous variations.

Others differences have only a very few possible options, these are called discontinuous variations.

Continuous variation

Some of these differences vary over a whole range, for example the height, skin colour and weight of people. We call this type continuous variation.

So if you lined up a hundred people you would find a whole range of heights - within sensible limits! People don't just come in set heights like shoe sizes.
