ABSTRACT
This chapter shows that how-to guide for inferential statistics. Political polling is based on the bell curve, sampling, error, and inferential statistics. The commentators were more than likely getting this information from a t-test or a more advanced statistical test that was operating like a t-test. A one-way analysis of variance has many characteristics similar to a t-test. In inferential statistics, the effect size measures the strength of relationship between two variables. The statistic provides a standard metric for comparison across studies. Chi-squares are regularly used in communication research, and in business, advertising and marketing. S. Steimel uses Chi-square to explore memorable messages that volunteers receive from the organizations they serve and how these messages relate to the volunteer experience. A correlation is a statistical measure of the degree to which two or more variables in a sample are related to one another. A positive correlation occurs when both variables move in the same direction.
