Test 2 results and scale

Here are the results of test 2:

Out of 25 points:

average = 18.07 (72.26%)
median = 18.5 (74%)
st.dev. = 2.95 (11.79%)

Here is an approximate grade scale (frequencies in parentheses):

(3) A: 21+
(9) B: 18.5 - 20.5
(7) C: 15.5 - 18
(4) D: 12.5 - 15 (originally 17.5, that was a typo. Thanks JC.)
(0) F: 12 and lower

There will be a discussion of the distribution of grades at the halfway point once the second paper is finished being scored.
