Test 1 grade distribution

Here is some information regarding the first test.

Out of a possible 30 points:

average = 22.07 (73.6%)
median = 23 (76.67%)
modes = 22, 23 (each has 3 observations)
standard deviation = 3.49 (11.63%)

Given that the average/median are below 80%, you can use the following "curve" to interpret your score. (Bear in mind, I only record raw scores and these scores are appropriately weighted given the number of points on the test and the point value of the test as declared on the course syllabus. I do not record letter grades for tests.)

A range: 25.5 and higher
B range: 22.5 to 25
C range: 18.5 to 22
D range: 15-18
F range: below 15 points (15 points is 50%, a very reasonable cut off for a passing score.)

The number of A and B range scores outnumber the C, D, and F range scores. So the distribution is a bit top heavy.

For those with good scores, keep up the good work. If you did not get the score you desired, I would hope you spend a bit more time and concentration with the material for the next test (Friday, October 22).
