Psychological Tests and Measurement
The Formal Grading System
for undergraduates Psychology 531:
There are three evaluated
components in the grade:
- Quizzes: Did you read the book?
- "The project": Can you construct a psychological measurement
instrument, and report thereon?
- The final: Required by UNC.
The three will be combined
into a final grade, by converting the corresponding letter grades into their
4-point numerical equivalents (A=4, B=3, C=2, D=1, and F=0) and computing the
arithmetic average. Recoversion to letter grades is as follows:
- A: Average > 3.5; e.g., AAA = (4+4+4)/3 = 4->A; AAB =
(4+4+3)/3 = 3.67->A
- B: Average > 2.5; e.g., BBB = (3+3+3)/3 = 3->B; ABB =
(4+3+3)/3 = 3.33->B
- C: Average > 1.5; e.g., CCC = (2+2+2)/3 = 2->C; BCC =
(3+2+2)/3 = 2.33->C
- D: Average > 0.5; e.g., DDD = (1+1+1)/3 = 1->D; DCD =
(1+2+1)/3 = 1.33->D
- F: worse
Turning quizzes into letter
- A: average number-wrong less than 1.5/quiz
- B: average number-wrong less than 3/quiz
- C: average number-wrong less than 4.5/quiz
- D: worse
Turning the project into
This will be set forth with
the project specifications, in March.
Turning the final into
- A: greater than 90% of maximum-raw-score-obtained
- B: greater than 80% of maximum-raw-score-obtained
- C: greater than 70% of maximum-raw-score-obtained
- D: greater than 60% of maximum-raw-score-obtained
- F: worse
(In addition to the usual
number-correct score on the final, there will be "extra credit"
points based on the performance of the items that you will write for the
