Standard deviation tells you how much the numbers in a dataset vary (spread out) from the average (mean).STDEV.S calculates the sample standard deviation, assuming your data is a sample from a larger population. illustration Patreon and LinkedIn links LinkedIn Profile /usmanzafarparacha /usmanzafarparacha /usmanzafarparacha LinkedIn Patreon profile /uzparacha /uzparacha /uzparacha Patreon Usman Zafar Paracha 1 Usman Zafar Paracha Usman Zafar Paracha example example example Usman Zafar Paracha 2 Usman Zafar Paracha Usman Zafar Paracha Suppose we have this data Suppose we have this data Suppose we have this data Then then then gives gives gives This shows that the numbers vary from the mean value by about 1.549 units on average.
