Dictionaries - Easton's Bible Dictionary - Diana. Diana [N] [H] [S] so called by the Romans; called Artemis by the Greeks, the great goddess worshipped among heathen nations under various modifications. Her most noted temple was that at Ephesus. It was built outside the city walls, and was one of the seven wonders of the ancient world.
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.
The t-test does just this. The formula for the t-test is a ratio. The top part of the ratio is just the difference between the two means or averages. The bottom part is a measure of the variability or dispersion of the scores.
