We hear a lot about things being correlated but often there is not a proper understanding of correlation according to statistics. This week is about simple inferential tests; you will gain a basic understanding of when to use what tests to measure, for example, something like correlation.

Respond to the following :

• When was the last time you heard a reference to something being correlated?
• In the context you heard it, what was the person trying to tell you?
• Did they explain why it was correlated?
