One instance in which you'll be viewing score percentiles is when you look at school rankings to figure out whether or not you even have a shot at getting in your school of choice. Let's say you're looking at the SAT scores for the Really Prestigious School you're thinking about attending, and you find yourself staring at this information from last year's incoming freshman when you peruse their website:
25th percentile scores for incoming freshmen: 1400
75th percentile scores for incoming freshmen: 1570
What does this mean? 25th percentile means that 25% of the accepted students made a 1400 or below on the test. It also means that 75% of the accepted students scored above a 1400. 75th percentile means that 75% of the accepted students made a 1570 or below on the test and that 25% of the accepted students scored above a 1570
The percentile rank formula is: R = P / 100 (N + 1). R represents the rank order of the score. P represents the percentile rank. N represents the number of scores in the distribution.
And speaking of scores, if you're on a date while riding in my limo, please don't ask me if people have ever had sex in the back of the car. The answer is always yes. Every time. Be safe, kids!
