edu.grading-curve Calculator
Applies a class-average grading curve to a set of raw scores, scaling all grades up by the difference between the target mean and the actual class mean. Curving is most common in large lecture courses where raw scores fall well below target averages.
Inputs
Raw Score
Reference formula or conversion factor shown for context.
Class Mean
Arithmetic average. Sensitive to outliers — if your data has extreme values, the median may be more representative.
Class Sd
Reference formula or conversion factor shown for context.
Target Mean
Arithmetic average. Sensitive to outliers — if your data has extreme values, the median may be more representative.
Results
curved score
A numerical rating from the scoring model in use.
letter grade
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
z-score
Number of standard deviations a value is from the mean. |z| below 2: within normal range. |z| above 2: in the outer 5% of the distribution. |z| above 3: in the outer 0.3%.
class shift
The classification assigned based on the computed value.
raw score percentile
The value below which the given percentage of the data falls. The 90th percentile means 90% of values are below this point.
