On the SATs, students can be compared to a recent norm group by examining their percentile score, or an earlier norm group by examining their standard score. The earlier standard score used a mean of 500 and a standard deviation of 100.
Standard Deviation
A measure of variability that describes how scores vary around the mean. In all normal curves the percentage of scores between standard deviation units are the same; hence, the standard deviation combined with the mean can tell us a great deal about a set of test scores.
Percentile Score
A score indicating the percentage of scores in a distribution that a specific score is equal to or higher than.

Final Answer :
True
Explanation :
This statement is true. Up until March 2016, the SAT used a scoring system with a mean of 500 and a standard deviation of 100. This means that a standard score of 500 was considered average, and scores above or below 500 deviated from the average by a certain number of standard deviations. However, the SAT's scoring system changed in 2016, and now uses a different range of scores and a different scoring system.
