Question

With respect to the measurements taken, between-subjects designs are to designs are to ______________ as within-subjects designs are to _________. a. dependent measures, repeated measures b. dependent measures, independent measures c. repeated measures, independent measures d. independent measures, repeated measures All of the following apply to the concept of pooled variance EXCEPT: a. it s used m between-subjects t-tests b. it is obtained by averaging two separate sample variances c. it allows the bigger sample to carry more weight in determining the final value for variance d. it is used in repeated measures t-tests With respect to t-tests, between-subjects designs utilizing the t-statistic: a. include one sample, in which each participant is measured more than once b. include one sample, in which each participant is measured only once c. include two samples, in which each participant is measured more than once d. include two samples, in which each participant is measured only once A primary disadvantage of repeated-measures t-tests is: a. there is no way to control for individual differences b. the order in which treatments are presented (or practice) may influence the treatment effect c. less subjects are needed for equivalent degrees of statistical power d. these designs have NO disadvantages What is the primary purpose for the technique of counterbalancing? a, to control for order and/or practice effects b. to control for individual differences c. to control the shape of the population distribution d. to control for placebo effects D-scores measure differences between: a. two separate raw scores from two separate samples b. two related raw scores from the same individual c. three separate raw scores from three separate samples d. none of the above With respect to the repeated measures t-test, from what population are we inferring statistical information about? a. a population of raw scores (X's) b. a population of variance ratios (F's) c. a population of difference scores (D's) d. none of the above A repeated measures t-test may be used for which type of research design? a. between-subjects b. matched-subjects c. within-subjects d both answers band c

Explanation / Answer

Ans:

between subjects means independent measures

within subject means repeated measures

25)Independent measures,repeated measures.(Option d is correct.)

26)Option d is correct.(as,it is used only in independent measures t test)

27)Option d is correct.(two samples,in which each participant is measured only once)

28)Option b is correct.

29)To control for order or practice effects(option a is correct).

30)two related raw score from the same indvidual.(option b is correct)

31)a population of difference scores.(option c is correct)

32)matched subjects and within subjects.(option d is correct)
