Confidence Intervals and Hypothesis Testing

In this topic, students learn the theory and methods of confidence intervals and hypothesis testing. Confidence intervals assess how well a sample statistic estimates the corresponding population value (U.S. National Institute of Standards and Technology). Hypothesis testing is a related component that assesses whether there is a statistically significant difference between the treatment group and control group in an experiment.

Topic Learning Outcome: Students will have a working knowledge of how researchers test hypotheses, and will be able to perform hypothesis tests of their own using statistical software.

Sample Assessment Questions:

1.) What is a P-value? Why is this statistic important for confidence testing?

2.) What does the term "statistical significance at the 5 percent level" mean?
