The formula for calculating a T-score is: T-score = 50 + [10 x ((raw score â mean)/SD)]. The mean and SD for a pre-clinical course are based on students taking the course during the same offering (time period). For clerkships, the mean and SD are based on active students applying for residency in the same year.
Statistical Analysis of the T-Test. The formula used to calculate the test is a ratio: The top portion of the ratio is the easiest portion to calculate and understand, as it is simply the difference between the means or averages of the two samples. The lower half of the ratio is a measurement of the dispersion, or variability, of the scores.
