Using the accompanying Student Grades data, construct a scatter
chart for midterm versus final exam grades and add a linear
trendline. What is the model? If a student scores 7878 on the
midterm, what would you predict her grade on the final exam to
be?

Since we are attempting to examine the behavior of a class of
students, the behavior of an individual (as we calculated in
objective 1) is really of little concern to us. Assuming that there
are 30 students enrolled for a typical class, use the central limit
theorem to calculate the following:
• What would be the shape of the
distribution of the average class grade of these 30 students?
• What would be the average class
average of...

The Data
A central tenet to being a good instructor, I believe, is to be a
reflective practitioner of your craft. From time to time I find it
to be necessary to review and reflect on my work as an instructor
from a grade perspective. On our moodle page you will find a link
to a second word document titled “300 Grades”. This data sheet
contains both the alphanumeric grade (page 1) and the numerical
equivalent (page 2) for every...
