Graphing hypothesis testing
WebTo decide if a one-tailed test can be used, one has to have some extra information about the experiment to know the direction from the mean (H1: drug lowers the response time). If the direction of the effect is unknown, a two tailed test has to be used, and the H1 must be stated in a way where the direction of the effect is left uncertain (H1 ...
