# CSE 30 -- Grades Distribution

## Assignment 1

The grade distribution is given by the following plot:

where the column indices are the score in 10s of points (so column 9 correspond to scores of 90 and higher), and the height of the column represent the number of people with that score.

There are several handins that were similar or identical. For those of you who received a zero and believe that the similarity between your homework and the other person's was accidental, you should come talk to me.

## Assignment 2

The following bar chart gives the grade distribution:

## Assignment 3

The following bar chart gives the grade distribution:

## Midterm

The following bar chart gives the grade distribution:

Midterm, with answers are available. I did not expect you to finish it. The stats to the midterm is available. The midterm grade distribution is:

If I were to assign a letter grade on the midterm (not really useful, since at the end of the quarter I will simply add the numeric scores together as weighed by the relative worth of homework/midterm/final), I would (roughly) give the people with more than 80 points an A, those with more than 60 points a B, those with more than 40 points a C, and the remainder a D.

A sample solution for assignment 5 is available. The comments are a little different that what I expect from you, since they are more pedagogical in nature -- pay attention to the stuff about the delay slots.
