Document Summary

Here we want to calculate a percentile, given a raw score. First thing to gure out is how many applicants we"re looking at. What is the position of the 85th percentile: 40 x 85th percentile = 34, count the cumulative frequency from the bottom up, till you see which interval the. Since my number is in the 7th interval, the fb is the 6 intervals under it summed up: 3 is the interval width. 26 means that anyone who scores 26 or lower is cut from the percentile, and does not get the scholarship. Z= raw score - xbar (mean) / standard deviation. Example: mean of 5+-1, with a raw score of 6: 6-5/ 1 = +-1 sd. Pay attention to whether your raw score is greater than the mean. If it is then your score will be positive, if not then your score will be negative.
