Answer #1

Here we have given : for an independent samples one way ANOVA test :

F(4,40) = 4.56

That is here degree of freedom for between group is 4 hence there is five independent samples . and error df is 40

Q . How many unique, nonindependent post-hoc pairwise comparisons could be conducted if this test was statistically significant?

we can do 10 unique , non independent post hoc pairwise comparison if the test is statistically significant .

1) test for (x1 - x2)

2) test for (x1 - x3)

3) test for (x1 - x4)

4) test for (x1 - x5)

5) test for (x2 - x3)

6) test for (x2 - x4)

7) test for (x2 - x5)

8) test for (x3 - x4)

9) test for (x3 - x5)

10) test for (x4 - x5)

5). Finally, which of the following would you use to write out the results in an APA formatted results section? A. We ran a One Way ANOVA with time as our independent variable and willingness as our dependent variable. The One Way ANOVA was not significant, F(2, 87) = 364.01, p > .05. Thus participants were equally willing to do the study in the 5 minute condition (M = 7.93, SD = 0.73), the 60 minute condition (M = 2.07,...

You conducted a t-test in your 691 capstone research. You did not find a statistically significant difference between your groups even though your sample size was relatively small. Upon conducting a post hoc power analysis you found that your actual power was 0.57. What should you do? Is there a problem with having a power less than 0.80 when you do not have significant differences?
