The formula to calculate the R Score is:
\[ R = Z + 5 \]
Where:
Let's say a student's average grade is 85, the class average is 75, and the standard deviation is 10. The Z-Score and R Score would be calculated as follows:
\[ Z = \frac{85 - 75}{10} = 1 \]
\[ R = 1 + 5 = 6 \]
So, the R Score is 6.
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.
