Symmetric difference - Study guides, Class notes & Summaries

A/B Test - 1) An experiment that compares the value of a dependent variable (ex = likelihood that a website visitor purchases an item) across two different groups (control group and treatment group). Members of each group must be RANDOMLY SELECTED to ensure that the only difference between the groups is the "MANIPULATED" independent variable (ex = size of the font on two otherwise identical websites)...a hypothesis test that tests whether the means of the dependent variable are the same across t...
