In what situation should you use the sign test or Tukey test in lieu of a higher power test such as the Z or t-test?
Homework Answers
When there are multiple treatments, Tukey test is more reliable. For example, there are 4 treatments to determine significant differences between the groups. In t-test, the comparison will be between two of the four groups, whereas in the Tukey test the comparisons will be with all possible pairs. So the result will be more reliable and precise.
Hope this will help you.

According to the book, what should you consider if you are selecting independent variables for a multiple regression model? Multiple Choice The logical selection will be based on the algebraic sign for each variable in the model. The overlap in two or more independent variables will influence the dependent variable. The coefficient of determination should be used to determine the explanatory power of the model. The selection should be based on an understanding of the nature of the situation
