Plug in x values for standard deviation
WebbIn summary, the procedure to calculate the standard deviation depends on whether the numbers are the entire population or are data from a sample. The calculations are the same except that for the sample we divide by "sample size - 1: n-1" and for the population we divide by "Population size N". Webb6 juni 2015 · 4.
