Description

This video takes a look at how we decide which of the measures of centre we are best using. We can choose between the Median and the Mean. The video looks at what each of these mean and how we can decide which to use depending on whether the data is symmetrical or skewed. Examples are given which highlight the differences. I then move on to how to find the mean using both the old ways and the new formula before moving onto the ideas of Standard Deviation. I show how to find the Standard Deviation using the CAS and explain why it's going to be important to know.
