Hypothesis Testing Summary - Indiana University …
C:\rsm\y520\sec5982_fall02\week_12\ Testing Summary Hypothesis Testing begins with the drawing of a sample and calculating its characteristics (aka, statistics ). A statistical test (a specific form of a Hypothesis test) is an inferential pro-cess, based on probability, and is used to draw conclusions about the population parame-ters. One way to clarity the process of Hypothesis Testing is to imagine that you have first of all, a population to which no treatment has been applied (aka, comparison group ). You know the parameters of this population (for example, the mean and standard deviation). Another population exists that is the same as the first, except that some treatment has been applied (aka, the treatment or experimental group). You do not know the parameters of this are drawn from this latter population and the statistics derived from the sample serve as the estimates of the unknown population parameters.
