Question

Question 1

For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc

1. True
2. False

Question 2

For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc.

1. True
2. False

Question 3

Both ANOVA and Chi square tests are always right tail tests

1. True
2. False

Question 4

For ANOVA, you only complete a Tukey's means comparisons test if the overall F* value was significant (i.e., p<0.05)

1. True
2. False

Question 5

Both F and Chi Square distributions vary with df

1. True
2. False

Question 7

A researcher convinces 15 students to partake in her study to see if the 3 methods of shock therapy, electrolyte therapy, and osmosis can affect students’ test scores. She randomly assigns 5 students to each method. Given SSTreatment = 2510 and SSError = 160, find F statistic. Round to the nearest tenths.

For ANOVA, if you reject the null hypothesis, then you know that all the means are significantly different from each other.

1. True
2. False

Question 9

You want to compare 3 means. If you DON'T use ANOVA and instead use 3 separate t-tests, the probability of a Type I error rate is still 5%

1. True
2. False
