Question: What is discontinuous variation?

Faye Didymus answered on 15 May 2012:

Great question! Discontinuous variation is where people fall into a number of distinct classes or categories. It’s based on features that cannot be measured across a complete range…you either have the characteristic or you don’t. Blood groups are a good example of discontinous variation because you are either one blood group or another – you can’t be in between. Data (information) that relates to discontinuous variation is called discrete (or categorical) data. I hope that answers your question!
