“STDEV”表示“标准差”,Stand Deviation “S”表示“样本”,即 Sample “P”表示“全体”,即 Population 选择S还是P,其实就是标准差公式中分母是"n-1"还是"n"的问题,为什么是“n-1”涉及到无偏估计和有偏估计,这里不展开,改天专写一篇,单独讨论。 简单说,S用于小型样本,P用于大型样本或者全体。 那么样本...
(a count of items in the data set). Technically, this is referred to as "biased." Remembering that thePinSTDEVPstands for "population" may be helpful. Since the data set is not a mere sample, but constituted of ALL the actual values, this standard deviation function can return a more ...
n is the sample size (the number of data points in the sample). Since the divisor in the population standard deviation formula is N which is greater than the divisor for the sample standard deviation formula, n-1, the population standard deviation will always be smaller than the sample stand...
STDEV.P vs STDEV.S So, what are the difference in STDEV.P and STDEV.S function? Let’s Explore.The STDEV.P function is used when your data represents the entire population. The STDEV.S function is used when your data is a sample of the entire population.In...
