Unformatted text preview: Homework Grade Calculation The homework for EMA 4223 consisted of a qualitative metric where the TA graded on a scale from 0
4 points. The metric was defined as below: Grade 4 Perfect or pretty darn close to perfect with few minor errors 3 Great job with several minor errors 2 Good attempt with major errors 1 Major errors and clearly confused 0 Very little or no effort The 4
point grading scale was used on each of the nine homework given in class. The homework average was then calculated on the 4
point scale. Next, the 4
point based homework average was then converted to a numerical grade. Initially, the point
to
grade conversion that was discussed on the first day of class was the following: Homework GRADE Grading Scale A = 4.00
≥ 92
A = 3.67
≥ 88
B+ = 3.33
≥ 84
B = 3.00
≥ 80
B = 2.67
≥ 76
C+ = 2.33
≥ 72
C = 2.00
≥ 68
C = 1.67
≥ 65
D+ = 1.33
≥ 62
D = 1.00
≥ 59
D = 0.67
≥ 56
E = 0.00
< 56
In order to re
scale the grading scale (effectively curving the grades), the numerical scores shown above where shifted up by a letter grade creating the following point
to
grade conversion. Homework Grading Scale A = 4.00
A = 3.67
B+ = 3.33
B = 3.00
B = 2.67
C+ = 2.33
C = 2.00
C = 1.67
D+ = 1.33
D = 1.00
D = 0.67
E = 0.00 GRADE ≥ 100
≥ 92
≥ 88
≥ 84
≥ 80
≥ 76
≥ 72
≥ 68
≥ 65
≥ 62
≥ 59
< 56 This new grading scale creates the following relationship between points and numerical grades: Numerical Grade = 54 exp(0.15*points) Use the above formula to determine your homework grade. ...
