Question

1.) An F table shows the following two critical values: 2.96 and 4.60. Which of these values would be the critical value for a 0.01 error level?

a. 2.96.

b. 4.60.

c. There is not enough information to tell.

2.) When and why would you conduct post hoc tests as a follow up to the overall F test?

When the overall F test is NOT significant; to determine which of the pairs of groups may be significant.

When the overall F test is NOT significant; to determine why the overall F test is not significant.

When the overall F test is significant; to determine between which pairs of groups the significant difference lies.

d. When the overall F test IS significant; to determine if the significance is only the result of chance.

3.) The between sums of squares and within sums of squares must add to the total sums of squares.

True.

False.

True.

False.

When the overall F test is NOT significant; to determine which of the pairs of groups may be significant.

When the overall F test is NOT significant; to determine why the overall F test is not significant.

When the overall F test is significant; to determine between which pairs of groups the significant difference lies.

d. When the overall F test IS significant; to determine if the significance is only the result of chance.

3.) The between sums of squares and within sums of squares must add to the total sums of squares.

True.

False.

4.) The sum of within-groups variance and between-group variance is the total variance. a.

True.

False.

1)as from above we do not know degree of freedom

hence option c. There is not enough information to tell

3)true

4) false
