Document Summary
Know all about the different kinds of t-tests: single-sample, related-sample, and independent-measures, know how to calculate them, how t compares to z, which ones we use in which cases. Know about degrees of freedom and how to calculate for each test: know how this affects the test statistic. Know how to obtain critical t value for all tests and confidence intervals. Given a critical value and t value, be able to make decision on null or alternative hypotheses. Know about the standard error for each test: know how it is affected by things and affects other things. Know all about confidence intervals, point estimation: what affects confidence intervals, how to calculate and interpret them, why we use them. Know how to calculate cohen"s d for all tests.
