Question

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. Test 1 calculates group differences with a p value = .07. Test 2 calculates the strength of association between two variables with a p value = .50. Test 3 calculates group differences with a p value = .001. For each test below, state whether or not you reject the null hypothesis. For each test, also explain what your decision implies in terms of group differences (Test 1 and Test 3) and in terms of the strength of association between two variables (Test 2). Test 1 (group differences) = Test 2 (strength of association) = Test 3 (group differences) =

Answer 1

Test #1 (group differences) = The p-value of .07 is more than .05, therefore we would fail to reject the null hypothesis that assumes the criminal defendant is innocent until proven guilty.

Test #2 (strength of association) = The p-value of .50 is greater than .05, therefore we would fail to reject the null hypothesis that suggests at a significant level of .50 proves that the strongest association is concrete or evidence that job satisfaction or organizational citizenship behaviour are relatable and measurable variables.

Test 3 (group differences) = The p-value of .001 is less than .05, therefore we would reject the null hypothesis that suggests at a significant level of .50 proves that there is a significant difference between groups.
