Solved Calculating the percentile for a set of data
For example, the 95th percentile is the value that is greater than 95% of the data. Percentiles are often used to find outliers. In (statistically) normal distributions, the 0.13th and 99.87th percentiles represent three standard deviations from the mean.... The percentile rank and z-score of a measurement indicate its relative position with regard to the other measurements in a data set. The three quartiles divide a data set into fourths. The five-number summary and its associated box plot summarize the location and distribution of the data.

How Do You Calculate Percentile? Reference.com
A percentile is a value below which a given percentage of values in a data set fall. A percentile calculated with .4 as k means 40% percent of values are less than or equal to the calculated result, a percentile calculated with k = .9 means 90% percent of values are less than or … how to get alcohol underage on a cruise shi One measure often used is called the Percentile Rank (or PR). Note that the cumulative percent (C%) gives the PR or % falling at or below a given score. However, unlike the C% which is only given for the upper exact limit of the interval, we need to be able to compute this for any score.

- T-digest is a probabilistic data structure that is a sparse representation of the empirical cumulative distribution function (CDF) of a data set. T-digest is useful for computing approximations of rank-based statistics (such as percentiles and quantiles) from online or distributed data in a way that allows for controllable accuracy, particularly near the tails of the data distribution.
