Following the National Institute of Standards and Technology (NIST) "Engineering Statistics Handbook: Percentile" formula, the applicant pool is first ranked from lowest to highest value in each of the three categories, where 1 corresponds to the lowest rank. The formula then finds the rank n associated with each percentile cut-off as follows:
n = P/100 x (N + 1)
P is the percentile of interest. If there are ten possible point ranges for example, then P = 10 would correspond to the 10th percentile, P = 20th to the 20th percentile, and so forth, until the 100th percentile has been calculated. N is the total number of applicants in the current applicant pool.
The formula then uses a standard rounding and conversion procedure to turn the rank n into a monetary cut-off value. The Excel function PERCENTILE automatically does this calculation according to the same NIST formula (see citation: http://www.itl.nist.gov/div898/handbook/prc/section2/prc262.htm) The CFC shall use this Excel function to determine initial cut-offs, and then choose final cut-offs within +/- 10 percent of what the formula produces, such that the ranges can be rounded. Ranges may be adjusted for future application periods based on the data collected from previous application periods.
