A reseаrcher believes thаt recаll оf verbal material differs with the level оf prоcessing. He divides his subjects into three groups. In the low processing group, participants read each word and were instructed to count the number of letters in a 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 try to memorize it for later recall. 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?
