EDF
5400: INTRODUCTORY STATISTICS & DATA ANALYSIS
INSTRUCTOR:

I
use the following grading scale for nearly all assignments and for the
total final course grade:
Percentage:
95-100 A
90-94 A-
85-89 B+
80-84 B
75-79 B-
70-74 C+
65-69 C
Under 65...We'll talk. If you do all assignments,
this has a VERY low probability of occurrence.
This grading scheme will be used to assign APPROXIMATE letter grades to exams.
At
the end of the semester, the total points will be summed for all three
exams. A letter grade will be assigned to the
total exam point score (see below).It
PROBABLY will resemble the average letter grade of the three exams
(see below).
Each
assignment will receive a total point score. All assignment points will
be totalled and a letter grade will be assigned to the total assignment
score.
I
reference the Florida State University's system whereby:
A = 4.0
A- = 3.75
B+ = 3.25
B = 3 points
B- = 2.75
C+ = 2.25
C = 2.0 (and so on)
Thus, I add the grades in numeric scores equivalents for all assignments, then average them. Each assignment counts 5 percent.
TWO EXAMPLES
| Assignment | Student One | Student Two |
| One: Table Construction | 18 | 15 |
| Two: Central Tendency & Variation | 20 | 18 |
| Three: Bivariate Table; T-test | 19 | 18 |
| Four: Multivariate Table; Causal Issues | 19 | 19 |
| Five: Multiple Regression | 17 | 17 |
| Total percent | 93% A- 3.75 | 87% B+ 3.25 |
All assignments put together are 25 percent of the final grade.
NUMERIC
scores for all three exams are summed, producing a total exam score somewhere
from zero to 300.
Keeping the current letter grade equivalents:
285-300 = A
270-284 = A-
255-269 = B+
240-256 = B
under 240, the grade will depend on the total numeric score location
Then,
the grade for the assignments and the exams is weighted by its proportion
to the total grade:
Assignments
= .25
Exams
= .75
Each assignment or exam total is multiplied
by its corresponding weight.
The products are summed.
EXAMPLE: STUDENT ONE
| Assignments | A- (3.75) X 0.25 | 0.9375 |
| Exams | B+ (3.25) X 0.75 | 2.4375 |
Total = 3.375 or a B+ final course grade for Student One.
EXAMPLE: STUDENT TWO
| Assignment 1 | B+ (3.25) X 0.25 | 0.8125 |
| Exams | A (4.00) X 0.75 | 3.0000 |
Total = 3.8125 or an A- final course grade for Student Two.
ADDITIONAL
NOTES:
For many students, the final letter grade is determined very straightforwardly using the formulas above. However, I reserve the discretion to consider the following, which may raise the final letter grade slightly:
Improvement
over the course of the semester. Several students in this course never
have had a previous course in statistics and the material is entirely
new to them. Thus, some students will show dramatic improvement over the
course of the semester as they gain familiarity with the terminology and
with analytic approaches.
A
strikingly excellent performance on one or more parts of an exam or
assignment.
Helpful
contributions to class meetings or clarifications on course material that
indicate the student is actively grappling with the material in depth.
I do not grade on a "curve." I do truly believe that one does not penalize
excellent work because an entire class did well. It is my goal for EVERYONE
to do well. And my experience is that this is absolutely possible.
I will be glad to go over
any of these points: 
PLEASE READ ALL GENERIC FEEDBACK FIRST
BEFORE ASKING QUESTIONS ABOUT RETURNED ASSIGNMENTS AND EXAMS.
