You may also like

Standard deviation is a statistical measure that represents the amount of variation or dispersion from the average value in a data set. It's a way to express the uncertainty or volatility of a data set, giving users a clear understanding of the range of possible outcomes. By calculating the standard deviation, you can determine the likelihood of a value deviating from the mean. For example, if a data set has a high standard deviation, it means the values are spread out and there's a higher chance of outliers.
