The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently the squares of the differences are added. The sum of the squares is then divided by the number of observations ...

More ### Standard Deviation Definition DeepAI

2021-6-14  Standard deviation is the measure of dispersion, or how spread out values are, in a dataset. It’s represented by the sigma (σ) symbol and found by taking the square root of the variance. The variance is just the average of the squared differences from the mean. Unlike variance, standard deviation is measured using the same units as the data.
