Notice that the mean on the second exam is nine points lower than that on the first exam.  I did caution the class that the second exam would be more difficult than the first.  I hoped that that caution would motivate most to put in more study time for the second exam.  I expect the third exam to be the most difficult of the semester, as it will include material on the brain and nervous system, topics many students find difficult.

    To determine your grade on the second exam, add 7 points to your score (assuming that you will satisfy the survey and research requirement, which constitutes 7% of your final grade).  If that yields 90 or more, you have an A, 80 or more a B, 70 or more a C, 60 or more a D, below 60 an F.

**. Correlation is significant at the 0.01 level (2-tailed).

    Notice that the correlation between the two exams is very high -- on average, students who did well on the first exam also did well on the second exam, and those who did poorly on the first exam also did poorly on the second exam.  This correlation is statistically significant.
