5

The "sensitivity" of an experiment refers to its ability to detect large effects of the independent variable.

Independent groups designs are less sensitive than repeated measures designs because there is typically more variability in responses between different people in conditions than there is variability within individuals.

False

9

Practice effects must be balanced in the independent groups design and the repeated measures design.

A)

True

B)

False

10

The complete repeated measures design is used when individuals participate in each condition of the independent variable more than once.

A)

True

B)

False

11

Practice effects in the complete repeated measures design are counterbalanced using all possible orders or selected orders.

A)

True

B)

False

12

In ABBA counterbalancing a random order of conditions is presented twice.

A)

True

B)

False

13

In a complete repeated measures design practice effects are balanced within each individual.

A)

True

B)

False

14

In an incomplete repeated measures design each participant experiences only one level of the independent variable exactly once.

A)

True

B)

False

15

When there are four or fewer conditions of an independent variable in an incomplete repeated measures design it is best to use all possible orders for presenting the conditions.

A)

True

B)

False

16

Data analysis for the complete repeated measures design requires the additional step of computing a summary score for participants' performance in each condition of the experiment.

A)

True

B)

False

17

The logic of inferential statistics for the repeated measures design differs from the logic used for independent groups designs.

A)

True

B)

False

18

Differential transfer occurs when the effects of one condition persist to influence participants' experience of subsequent conditions in the experiment.

A)

True

B)

False

19

Similar to practice effects, the problem of differential transfer in a repeated measures experiment is controlled through counterbalancing.

A)

True

B)

False

20

The effects of differential transfer can be eliminated in a repeated measures design but not in a random groups design.

A)

True

B)

False

21

A repeated measures design is an experiment in which individuals participate in each condition of the independent variable.

A)

True

B)

False

22

The effects of individual differences variables in the repeated measures design are averaged across conditions using counterbalancing.

A)

True

B)

False

23

Practice effects are eliminated in the repeated measures design through counterbalancing.

A)

True

B)

False

24

A disadvantage of the repeated measures design is that it is less sensitive than the independent groups design.

A)

True

B)

False

25

The less the variability in participants' responses within the conditions of an experiment, the greater the sensitivity of the experiment.

A)

True

B)

False

26

A repeated measures design differs from a longitudinal survey design because an independent variable is manipulated in a repeated measures design but typically not in a longitudinal survey.

A)

True

B)

False

27

A major problem in repeated measures design is due to the confounding of individual differences variables with the levels of the independent variable.

A)

True

B)

False

28

Both independent groups designs and repeated measures designs require that potential confounding variables be controlled through balancing; however, the nature of the confounding variables differs.

A)

True

B)

False

29

"Practice effects" refer to the potential problem that participants' performance always improves across the conditions of a repeated measures design.

A)

True

B)

False

30

In an incomplete repeated measures design, participants experience some of the conditions of the independent variable, but not all of them.

A)

True

B)

False

31

Block randomization is the preferred counterbalancing technique in the complete repeated measures design when anticipation effects are likely or practice effects are nonlinear.

A)

True

B)

False

32

"Linear practice effects" refers to the idea that each presentation of a condition in the experiment adds the same amount of practice.

A)

True

B)

False

33

In an incomplete repeated measures design practice effects are balanced for each participant.

A)

True

B)

False

34

The rule for balancing practice effects in an incomplete repeated measures design is that each condition of the independent variable must be presented in each ordinal position (1st, 2nd, etc.) equally often.

A)

True

B)

False

35

In an incomplete repeated measures design that uses all possible orders of the conditions, each participant experiences all of the possible orders.

A)

True

B)

False

36

Random starting order with rotation and Latin Square are two methods for creating selected orders of conditions of the independent variable in an incomplete repeated measures design.

A)

True

B)

False

37

An advantage of the "random starting order with rotation" method for selecting orders of presentation is that each condition precedes and follows every other condition equally often.

A)

True

B)

False

38

The error variation in the statistics for a repeated measures design is generally less than the error variation for the same variables when manipulated in an independent groups design.

A)

True

B)

False

39

A researcher who tests the effects of alcohol vs. no-alcohol conditions in a repeated measures design should be aware of the problem of differential transfer.

A)

True

B)

False

40

One way to determine whether differential transfer is a problem in a repeated measures design is to replicate the repeated measures design to see if the same results are observed.

A)

True

B)

False
