Hello stats course members, and welcome to episode #4! In this episode, we spend a little over 20 minutes talking about different measures of variation or the measures we can use to understand how different the values in our dataset are from one another. The statistical measures we use for understanding variation include the range, standard deviation, and variance. We will go over the definition/explanation of each term and then we will do some practice (both by hand and in SPSS) for calculating standard deviation and variance. As always, let me know of any questions or concerns and I'll get back to you as soon as I can with more clarification and guidance!
