Week 10:  Repeated Measures Designs

SHORT-ANSWER

1.   Cite at least two reasons why a researcher might choose to use a repeated measures design.

2.   Provide brief answers to each of the following questions regarding the repeated measures designs.

      A.  What distinguishes the complete repeated measures design from the incomplete repeated measures design?

      B.  What techniques are used in the complete and incomplete repeated measures designs to balance practice effects?

MULTIPLE-CHOICE

3.   Which of the following is not one of the reasons why researchers choose to use the repeated measures design?

      A.  Repeated measures designs are generally less sensitive than are independent groups designs.

      B.  Repeated measures designs require fewer subjects.

      C.  Repeated measures designs are more convenient and efficient.

      D.  Repeated measures designs are needed when the experimental procedures require participants to compare two or more stimuli.

4.   The difference between repeated measurements to establish test-retest reliability and experiments using repeated measures designs is that in experiments with repeated measures designs:

      A.  measurements are compared for different conditions of an independent variable.

      B.  the reliability of measurement is not important.

      C.  measurements occur only twice.

      D.  a correlation coefficient would be used to determine consistency across measurements.

5.   There can be no confounding by individual differences variables in the repeated measures designs because:

      A.  only one participant is tested in all repeated measures designs.

      B.  individual differences variables are held constant in repeated measures designs.

      C.  individual differences variables are eliminated in repeated measures designs.

      D.  the same participants are tested in all conditions of repeated measures designs.

6.   Which of the following concerns leads researchers to balance practice effects in repeated measures designs?

      A.  Balancing practice effects allows researchers to determine the sources of systematic error variation in repeated measures designs.

      B.  Balancing practice effects allows researchers to account for individual differences variables in repeated measures designs due to participants' prior experience.

      C.  Balancing allows researchers to control changes participants undergo with repeated testing in repeated measures designs.

      D.  Balancing allows researchers to ignore sources of confounding that cannot be balanced in repeated measures designs.
