Question

Question 25 2 pts A researcher believes that recall of verbal material differs with the level of processing. He divided his subjects into three groups and manipulated the level of processing they used when learning a list of words. In the 'low processing group, participant read each word and were instructed to count the number of letters in the word. In the "medium processing group, participants were asked to read each word and think of a word that rhymed. In the "high processing group, participants were asked to read each word and use it in a sentence. Each group was allowed to read the list of 30 words three times, then they were asked to recall as many of the words on the list as possible. If the researcher wants to know whether the three groups have different amounts of recall, what type of statistical test should be used? a One-factor between subjects ANOVA b. Chi-square test for independence c. Repeated-measures ANOVA d. Related-samples t-test

Answer 1

Answer 25: One-factor between-subjects ANOVA

Explanation: In this case, there is only one factor that is level of processing. This factor has three levels: Low processing, medium processing, and high processing. The outcome variable is the no. of words recalled. Here, ANOVA is suitable as comparison has to be made between more than two groups.
