Independent-measures design: t-statistic for an independent-measures design, hypothesis test and effect size (independent measures, assumptions underlying the independent-measures t-test. Related-measures design: t-statistic for related-measures design, hypothesis test and effect size (related measures, uses and assumptions of related-measures t-test, overview of t-tests: types of t-tests. Denominator = estimated standard error of the relevant distribution. When conducting t-test, assume: the t-test is used to compare only 2 means.
