Question 3

Correct Answer:

Verified

In a random groups design the researcher manipulates the independent variable such that different groups of participants experience each level of the independent variable.Individual differences among participants across the conditions of the experiment must be balanced;random assignment to conditions is the preferred method for balancing individual differences variables.In the repeated measures design the independent variable is manipulated such that the same group of participants experiences every condition of the experiment.Practice effects due to repeated measurement must be counterbalanced in repeated measures designs.In the complete repeated measures design,in which each participants experiences every condition more than once,ABBA counterbalancing or block randomization may be used to balance practice effects across conditions.In the incomplete design,in which each participant experiences every condition exactly once,all possible orders or selected orders may be used to balance practice effects.

Counterbalancing is an important research technique because it is used to

Question 6

A researcher designs an experiment with six conditions but each condition takes only a short amount of time to administer.The researcher has the opportunity,therefore,to administer many trials of each condition in the experiment.Which of the following techniques is likely to be most effective for balancing practice effects?

Question 7

A psychologist wishes to have participants rate two different sets of inkblots (labeled A and B) for their "emotionality." The inkblots differ in their use of color. Ten inkblots in set A are created in shades of gray; ten inkblots in set B use shades of red, blue, and yellow. The psychologist hypothesizes that color will influence participants' ratings of emotionality. Each participant will rate all twenty inkblots. -What is the independent variable in this experiment?

Question 15

A researcher plans to conduct a complete repeated measures design in which the independent variable is manipulated using four conditions that vary the level of violence depicted in a photograph (none,low,medium,high).There are 10 photographs in each of the four conditions.Each participant will rate each photo once and therefore make a total of 40 ratings.If the researcher wishes to have 80 ratings for each photo,how many participants should the researcher recruit?
