You are running a series of statistical tests in SPSS using the “standard” criterion for rejecting a null hypothesis. You obtain the following p values: (a) Test 1 calculates group differences with p = .07; (b) Test 2 calculates the strength of association between two variables  with  p = .50; and (c) Test 3 calculates group differences with  p = .001.

First, what is the “standard” criterion for rejecting the null hypothesis (what p value)? For each of the three tests, state whether or not you would reject the null hypothesis, and why you made that decision. Then, explain what your decision implies in terms of group differences (Test 1 and Test 3) and the strength of association between two variables (Test 2).
