This presentation focuses on what standard deviation really is. We look at some examples of data that all have the same mean, but where the variation in data is different. This enables us to see how the standard deviation can be useful and why we need to square the values before square rooting.
A good visual representation to enhance understanding of what the standard deviation of a set of data means.
