Test 3 results and current grade distribution

Econ 122 Test 3

Average = 29.522 (73.81%)
Median = 29 (72.50%)
Mode = 29 (72.50%)
Standard Deviation = 5.0744 (12.69%)

The following scale should be used as a guide (frequencies in parentheses):

A: 34.5 + (10)

B: 29 – 34 (17)

C: 24 – 28.5 (13)

D: 19 – 23.5 (3)

F: 18.5 and lower (2)


Updated grade distribution

Up to this point there are a total of 71 recorded points: 3 X 20 points for each test, 10 points for 9 homework assignments (one was worth 2 points), and one in-class participation credit point (a video).

Points remaining are a final exam (20 points), 5 homework points, and 4 participation credit points.

The total points recorded on your test paper do NOT include any extra credit points. All grade brackets are set without extra credit points. At the end of the semester after all points have been tabulated, the scale will be set, and then extra credit will be added and if you move into a higher test score bracket your grade will be upgraded accordingly.

Average = 56.205 out of 71 points (approx 79.29%)
Median = 55.39 points (approx 78.02%)
Standard deviation = 7.23 (approx. 10.19%)
This distribution is very close to the desired distribution of an 80% mean and a 10% standard deviation. It is converging nicely.

If I were giving grades today this is the scale that I would use (again, it does not include the extra credit points) and frequencies are in parentheses.

Out of 71 points:

A: 63.250 + (10)

B: 56.000 – 63.249 (11)

C: 48.750 – 55.99 (18)

D: 41.500 – 48.749 (5)

F: below 41.500 (1)

Please note: If you did not take one of the tests and you have to take the comprehensive final, your points and this scale is meaningless.

One more note: All of this is unofficial. The only things official are your points (if you believe they are incorrect please see me at my office).
