X is the data point

    The standard deviation variance formula is a statistical measure used to quantify the amount of variation or dispersion of a set of data from its average. It represents a way to explain how much individual data points are spread out from the mean (average). The lower the standard deviation, the more consistent the data points are around the mean. Conversely, a high standard deviation indicates that the data points are more spread out.
