Inference and Making Conclusions

What is the true mean height of all students at your school? What is the true proportion of Hershey’s Kisses that will land on their flat side when tossed on a table? Has the true mean carbon dioxide level of the atmosphere increased significantly over the last five years? Does a new brand of sunscreen perform significantly better on average than an old one? In M215 Inference and Making Conclusions, you will master the logic of inference, learn a couple of inference procedures, and make decisions after weighing the risks associated with them. You will calculate and interpret P-values with technology. The confidence intervals you calculate will help inform choices about significant changes. You will learn what Type I and Type II errors are, as well as evaluate which error is worse in the context. You will use bootstrapping to improve the accuracy of your inference procedures and will make decisions based on how a study is designed and how small your P-value is. Inference and conclusion-making are useful for careers in a variety of fields, like psychology, biology, advertising, and manufacturing.
