Overview: A study was conducted to try and strategy. There were two groups of students in introductory Spanish classes used in this study. Both groups were asked to memorize 50 new vocabulary words for a quiz on Friday, The first consisted of 45 students and they were given the list of words on Monday and studied all week, The other group consisted of 25 students and they were given the list of words on Thursday night and had to "cram" before the quiz the next day. The students were also re-tested the following Monday without notice. The numbers shown below represent the amount of questions they answered correctly. For our purposes, we are only going to focus on a random sample of 10 students from the "cramming" group.
