Does Grade Inflation Really Matter?

Consider the following article on Grade Inflation. Article
source:
http://www.slate.com/articles/life/do_the_math/2002/10/dont_worry_about_grade_inflation.html

The author argues that, in fact, it is not a big deal – and that
the general public has made much ado about nothing over the
issue.

You task is to address this issue: Is it a big deal or not? When
doing so, please address the following questions:

1. What statistical concept is the author referring to when he
makes the argument that grade inflation is no big deal?

2. What is the meaning and purpose of a grading system?

3. Why doesn’t our university use a +/- system like – almost –
everyone else? (but focus solely on this issue like previous
semesters
have).

4. What type of grading system would you prefer?
