What is the conservative critical F statistic if your sample size is 50 and you are comparing 3 groups of participants (at the .05 level)?
What is the critical F statistic value for the following F (4,70), use a .05 level of significance?
If you have an MS between of 3.1 and MS within groups of 0.3, what would your calculated F statistic be?
If you saw the result of ANOVA like this F(2,40) = 4.5, how many groups were in the study and how many participants were in the study?

Give an example of when you would use a one-way ANOVA. What is dependent and what is independent variable?

Chapter 12: What two reasons do we use for the F-Statistic for? What is the critical F value for a hypothesis test with a sample from 5 populations with 20 observations total. Use a .05 significance level. Given a calculated F value of 3.5, would you reject or fail to reject the null hypothesis with the critical F value from question 2?

What is the F statistic reported in appropriate APA style? What is your decision?

Computational problems: One-way ANOVA A researcher wants to investigate different formats for taking an exam. She randomly assigns one-third of the class to an open book exam, one-third to no notes, and one-third to one page of notes only. The data appear below. Use SPSS to analyze the data and answer the following questions. Be sure to include your SPSS output (you will need to copy/paste your ANOVA table into a Word document first). What is the F statistic reported...
