Quizplus · Accepted Answer

The test statistic is a numerical quantity computed from the data of a sample and is used in reaching a decision on whether or not to reject the null hypothesis. The critical value is a specific value used for comparison to the test statistic in determining whether to reject or fail to reject the null hypothesis. The significance level is a predetermined level of probability used for determining whether to reject the null hypothesis. A parameter is a numerical value that describes a population characteristic, rather than a sample characteristic.
