Question

n order to report the exact p value associated with the test statistic for an independent-samples t test, we need to:

A - record the value from the t table under the 0.05 p level.

B - compute Cohen's d.

C - record the value from the t table under the 0.01 p level.

D - use software to obtain the value.

For an independent-samples t test, there were 8 participants in Group 1 and 11 participants in Group 2. The critical cutoffs for a two-tailed test with alpha of 0.05 are:

A - -2.101 and 2.101

B - -2.120 and 2.120

C - -2.132 and 2.132

D - -2.110 and 2.110

The benefits of the within-groups design are seen, in the calculation of the F statistic, in that:

A - the denominator is smaller, resulting in a larger F value.

B - the numerator is larger, resulting in a larger F value.

C - the numerator is smaller, resulting in a smaller F value.

D - the denominator is larger, resulting in a smaller F value.

________ is the proportion of variance in the dependent variable that is accounted for by the independent variable.

A - z

B - t

C - R2

D - Cohen's d

________ is(are) an additional assumption that must be evaluated in a within-groups ANOVA.

A - Mean differences

B - Order effects

C - Sample size

D - Counterbalancing

A - record the value from the t table under the 0.05 p level.

B - compute Cohen's d.

C - record the value from the t table under the 0.01 p level.

D - use software to obtain the value.
