Enter the average grade, standard deviation, and class average into the calculator to determine the R Score. The R Score is a standardized measure used to compare student performance across different schools and programs.
R Score Formula
The following formula is used to calculate the R Score:
R = Z + 5
Where:
- R is the R Score
- Z is the Z-Score, calculated as (Average Grade – Class Average) / Standard Deviation
To calculate the R Score, first determine the Z-Score using the student’s average grade, the class average, and the standard deviation. Then add 5 to the Z-Score to find the R Score.
What is an R Score?
The R Score is a statistical measure used in some educational systems, particularly in Quebec, Canada, to assess a student’s academic performance relative to their peers. It takes into account the student’s average grade, the average grade of the class, and the distribution of grades within the class, as represented by the standard deviation. The R Score is designed to provide a fair comparison of student achievement across different schools and programs with varying levels of grade distribution and difficulty.
How to Calculate an R Score?
The following steps outline how to calculate the R Score:
- First, determine the student’s average grade.
- Next, determine the class average grade.
- Then, determine the standard deviation of the class grades.
- Calculate the Z-Score using the formula: Z = (Average Grade – Class Average) / Standard Deviation.
- Add 5 to the Z-Score to get the R Score: R = Z + 5.
- Use the calculator above to verify your calculations.
Example Problem:
Use the following variables as an example problem to test your knowledge:
Average Grade = 85%
Class Average = 75%
Standard Deviation = 10
