To find percentile you need to first arrange the given data in ascending order

if you have a data set with n samples this is how you find the pth percentile. order the data set in ascending order use this equation to find the index of the percentile p/100 * (n + 1) if the soluition is an integer, say 32, then the pth percentile value is the 32nd data point from the sample in ascending order. if the solution is not an integer then you find the average value be the two surrounding points. for example, say the solution is 23.7 for the index of the pth percentile. the value reported is the average of the 23rd and 24th data point. This can be either the simple average or a weighted average. ^^I got that from yahoo answers .Its explained nicely
