This video is an introduction to statistics. We discuss what exactly the study of statistics is, the different steps involved, and how we can use certain measures or data displays to help explain a set of data. We talk more specifically about identifying statistical questions, making dot plots, identifying clusters, peaks, and gaps, and interpreting that information to answer a statistical question.
