1. The F ratio may be used to assess difference between (among):

a. two sample means b. three sample means c. four sample means d. All of these

3. With a two-group experimental design, the independent variable has been manipulated at:

a. one level b. two levels c. three levels d. all of these

4. For the F ratio, if alpha is set at .05, it remains at .05 of comparisons are made between (among)

a. 2 group means b. 10 group means c. 45 group means d. all of these

7. When the SS, sum of squares, is large, so too is the:

a. standard deviation b. variance c. both of these d. neither of these

9. The concept of “between variability” is based on:

a. how far the scores in all groups deviate from the total mean b. how far the scores in a single group deviate from their own group mean d. all of these, depending on the between degrees of freedom.

Homework Answers

Answer #1

1. F ratio is used to access the difference bet two or more measn

Option d is correct.

3. Option B is correct.

4. Alpha is remains same

Option d is correct.

7. The sum of squares measures the deviation of data points away from the mean value. A higher sum-of-squares result indicates a large degree of variability within the data set, while a lower result indicates that the data does vary considerably from the mean value.

Option C is correct.

9. at two or more levels. The concept of "between variability" is based on. how far each sample mean deviates from the total mean.

Option A is correct.

In testing the difference between two population means when population standard deviations are unknown, there are many cases depending upon whether the two population standard deviations are equal or not. Therefore, before testing the difference between two population means, the equality of two population variances must be tested first.
