Below is a smoothing of the pre-final course point totals for 120 students of 315 Fall 06.
Out of these 120 students there are 4 whose point total is already at least 134 points.
Bandwidth for this plot was set at sig = 5.
Below are 6 bootstraps of the above plot.
For the same 120 students I’ve made a plot of (x, y) pairs with
x = raw score on exam 1
y = pre-final point total for the course
The points were “jiggled about” a little bit at random so that people having exactly the
same scores would not perfectly overlap. That was of slight concern anyway because of
the relatively fine scale used for course point totals.
