Your study follows three groups of individuals and looks to see if the treatment you are offering has an effect. Your ANOVA results have an F-ratio that is smaller than the appropriate F-critical value. You know this means:

a.
None of the group mean values are equal



b.
At least one pair of group means is not equal

c.
The results are statistically non-significant.

d.
the correlation is significant

Answer #1

Our H0 will be

There is no significant difference between the treatments

Our H1 will be

There is atleast one pair of gorup mean which is statistically significant.

let our level of significance is alpha

and test statistic is F ratio.

so rejection criteria will be

Reject H0 if f ratio ( Calculated) > F ratio(tabulated).

according to question F-ratio that is smaller than the appropriate F-critical value hence we fail to reject the null hypothesis and conclude that there is no significant difference between the treatment.

Hence option c is correct

The results are statistically non-significant.

3. Suppose you are a researcher studying treatments for depression. Imagine three treatment groups (anti-depressant, therapy, and placebo) are being compared using Analysis of Variance. What effect would each of the following have on an F score (make it smaller, make it larger, or cause no change)? Explain why.

​​​​​​​Psychology Statistics You and a fellow student are comparing means for treatment and control groups, mT=7.56 and mC=4.78. You use a t-test, and get a statistic of t(45)=2.87, d=.856. Your colleague uses ANOVA, yielding an F statistic of F(1, 45)=8.27. It turns out that you accidentally switched which was group 1 and group 2, and your group means should have been mT=4.78 and mC=7.56. Does your t-statistic change? Does the F-statistic change? Does Cohen’s d change? Why or why not?
