Comments

Here's my mapping of scores to letter grades. I don't do B+/A's here -- what I do is convert each exam grade to the same scale as the labs, and then average them all.

• A+: 50 to 60
• A: 43 to 50
• B: 35 to 43
• C: 29 to 35
• D: 20 to 29
• F: Below 20

Please see the class web page on tests for information on the second midterm, which will be on 4/3.

Tukey Plots

This is a Tukey Plot, which has lines to the max and min, yellow box denoting the 1st and 3rd quartiles, hash marks at the median, and dot at the mean.

In the "answers and grading", there are histograms of scores for each question.
