Test #3 score distribution

The mean is lower than the previous tests, signifying the relative difficulty of the test. Or does it? The standard deviation is rather high. This signifies that some did very well on the test and others did really poor, relative to their performance on earlier tests. This seems to indicate that some of the "blame" is on some of you being less prepared than you were for earlier tests. Keep in mind that with a curve employed you might think that slacking is not very costly. I think that is quite the contrary. You ought to have incentive to slack less.

Here is the approximate grade scale. They are different depending on the section.

MWF 11:45 class

average = 25.8 out of 40 possible points (64.5%)
standard deviation = 4.46 (11.2%)

A range: 30+
B range: 26-29.5
C range: 21.5-25.5
D range: 18-21
F range: 17.5 and lower

MWF 1:00 class

average = 27.07 out of 40 possible points (67.7%)
standard deviation = 5.36 (13.4%)

A range: 32.5 +
B range: 27-32
C range: 21.5-26.5
D range: 21 and lower

Good luck with the rest of your semester.
