The alternative hypothesis for an independent group t test implies that there is a relationship between the independent variable (IV) and the dependent variable (DV). 3. Describe in your own words what the sampling distribution of the di ! erence between the mean is. 4. Can you think of a critical value as a minimum test statistic needed to reject the null hypothesis at your chosen alpha level? 5. If an IV has no e ! ect on the DV and sampling error alone is operating, we would expect the value of t to be large or small? 6. True/False. Adding a couple of outliers into a group would decrease the standard error of the di ! erence between the means. 7. True/False. The set of all t values more extreme than the critical values constitute an unexpected result, or formally, the rejection region. 8.
