question 21

Multiple Choice

Yvette, an investigator who is interested in the effectiveness of various memory strategies, instructs randomly assigned participants to use either imagery or repetitive silent speech to remember a list of 20 words. Two weeks later, she tests these participants for how many words they can recall. The imagery group recalls an average of 2.6 words, while the repetition group recalls an average of 1.9 words. She concludes that there is no difference in the effectiveness of these memory strategies because the results are not statistically significant. Is this a reasonable conclusion?

• A)Yes, because no significant results mean there is no relationship between the variables.
• B)Yes, because the level of processing memory is the same for all individuals.
• C)No, because the participants were randomly assigned to the groups.
• D)No, because a dependent variable measured after a two-week delay may lack the sensitivity to detect a difference.
