WebbThe standard deviation is a measure of how widely values are dispersed from the average value (the mean). Syntax STDEV.S (number1, [number2],...) The STDEV.S function syntax has the following arguments: Number1 Required. The first number argument corresponding to a sample of a population. Webb21 sep. 2024 · Standard deviation is commonly abbreviated as SD and denoted by “σ”. When your set of data points or values is far from the mean, this indicates a higher standard deviation. Conversely, a lower standard deviation indicates that your data points are closer to the mean. What does standard deviation tell you?
