Enter the Step 3 score, mean Step 3 score, and standard deviation of Step 3 scores into the calculator to determine the percentile rank.
Step 3 Percentile Formula
The following formula is used to calculate the Step 3 Percentile.
P = (S - M) / SD
Variables:
- P is the percentile rank
- S is the Step 3 score
- M is the mean Step 3 score
- SD is the standard deviation of Step 3 scores
To calculate the Step 3 Percentile, subtract the mean Step 3 score from the individual's Step 3 score. Then, divide the result by the standard deviation of Step 3 scores. The result is the percentile rank of the individual's Step 3 score.
What is a Step 3 Percentile?
A Step 3 Percentile is a statistical measure used in the United States Medical Licensing Examination (USMLE) Step 3 test to compare a candidate's performance to others. It indicates the percentage of test takers who scored lower than a particular score. For example, if a candidate's Step 3 Percentile is 90, it means that 90% of the test takers scored lower than this candidate. This percentile is used to evaluate a candidate's knowledge and skills in relation to the practice of medicine unsupervised.
How to Calculate Step 3 Percentile?
The following steps outline how to calculate the Step 3 Percentile using the given formula:
- First, determine the Step 3 score (S).
- Next, determine the mean Step 3 score (M).
- Next, determine the standard deviation of Step 3 scores (SD).
- Next, gather the formula from above = P = (S - M) / SD.
- Finally, calculate the Step 3 Percentile (P).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge:
Step 3 score (S) = 220
Mean Step 3 score (M) = 200
Standard deviation of Step 3 scores (SD) = 15
