We'll use a small data set of 6 scores to walk through the steps. The standard deviation calculator helps you to compute the population and sample standard deviation and variance with mean value. The 10th percentile is 1.28 times the standard deviation below the mean, so in your example (100 - 50) = 50 is 1.28 times the standard deviation which implies the standard deviation is equal to 50/1.28 = 39.06. In technical terms (I lost you there, I know), the sample mean is an unbiased point estimate of the population mean. Calculate any percentile and get a table of every 5th percentile for a given data set. Enter a data set and our percentile calculator finds the percentile you need.
