The percentile rank of a score is the percentage of scores in its frequency distribution that are equal to or lower than it. To find the percentile for 81.2, divide the number of points less than 81.2 by the total number of observations and multiply by 100. Thus, (186/300)*100 = 62. Therefore, 81.2 is at the 62nd percentile.
