math215 Lecture Notes - Lecture 2: Frequentist Probability, Venn Diagram, Mutual Exclusivity
Document Summary
Unit 1 introduced the two fields of statistics descriptive and inferential statistics but focused on descriptive statistics, which consists of the set of methods used to organize, display and describe data. The field of inferential statistics, you may recall, consists of methods that use sample results to make conclusions about a population of interest. Since we are relying on sample data, these conclusions are made with a level of uncertainty. Probability and probability distributions, the topics in the next two units of this course, help us determine the degree of certainty (or uncertainty) with which we can make conclusions about a population, based on observed sample results. After you complete units 2 and 3, you will be prepared to study many of the common methods that are used in the field of inferential statistics. Unit 2 examines the concepts and rules that allow us to compute the probabilities related to events that occur under conditions of uncertainty.
