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.
