Test 1 grade distribution

Here is the distribution of scores for test 1, with an approximate grade scale. I say approximate because no letter grade is recorded, only the raw score, which is appropriately weighted.

First, some descriptive statistics (out of a possible 35 points):

average = 26.21 (74.88%)
median = 27 (77.14%)
mode = 29 (82.86%)
standard deviation = 4.54

You can divide your raw score by 35 (and multiply by 100) to get your percentage score.

Based on the statistics above, here is, what I believe to be, a fair grade scale:

A range: 30.5 and higher (9 occurrences)
B range: 26.5 to 30 (17 occurrences)
C range: 21.5 to 26 (17 occurrences)
D range: 17 to 21 (3 occurrences)
F range: below 17 (2 occurrences)

Congratulations to those who did well. For those who did not perform as well as you would have liked, it is suggested you spend more time regularly with the material.
