Expected Learning Outcomes
By the end of this course a fully engaged student should be able to
1) determine when you need to use a t-test to help you test your hypothesis
2) determine which type of t-ttest you should use (i.e., one-tailed vs two-tailed test, paired vs unpaired test)
3) use Excel to perform a t-test on the computer
4) use the output of the statistical tests to correctly draw conclusions
