Cramming Students in two basic Spanish classes were required to learn 50 new vocabulary
Chapter 24, Problem 43(choose chapter or problem)
Cramming Students in two basic Spanish classes were required to learn 50 new vocabulary words. One group of 45 students received the list on Monday and studied the words all week. Statistics summarizing this groups scores on Fridays quiz are given. The other group of 25 students did not get the vocabulary list until Thursday. They also took the quiz on Friday, after cramming Thursday night. Then, when they returned to class the following Monday, they were retestedwithout advance warning. Both sets of test scores for these students are shown. a) Did the week-long study group have a mean score significantly higher than that of the overnight crammers? b) Was there a significant difference in the percentages of students who passed the quiz on Friday? c) Is there any evidence that when students cram for a test, their learning does not last for 3 days?
