The grade distributions are shown as stem and leaf plots.
For the distribution of the total scores, there is also a six number
summary (from the R `summary`

command).

The summary

Min. 1st Qu. Median Mean 3rd Qu. Max. 46.00 76.00 84.00 82.67 92.00 100.00

shows the lowest score, first quartile, median, mean, third quartile, and highest score.

The distribution follows (produced by the R `stem`

command).

For total score, the decimal point is one place to the right of the vertical bar

4 | 69 5 | 0467 6 | 044778 7 | 66666668888 8 | 000222244444444888888 9 | 02222222222222222222 10 | 00000000

Hence to the left of the vertical bar are the leading digits of the grades. To the right of the vertical bar are the last digits of the grades. Each single digit on the right represents one grade.

The bottom line says there were 8 perfect scores (100). The next to bottom line says there was one 90 and nineteen 92 scores. And so forth.

For individual questions, the decimal point is at the vertical bar

-4 | 0 -2 | 0000000000 -0 | 0 | 2 | 4 | 00 6 | 00000000000000000000000000000000000000000000000000000000000

The bottom line says there were 59 perfect scores (6). The next to bottom line says there were two 4 scores. And so forth.
