The unit of measurement commonly used to describe how far a set of values are from the mean is called the standard deviation.
Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a set of values. A low standard deviation means that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
In essence, standard deviation gives you an idea of how spread out the values are around the average. It helps in understanding the distribution of data points and is essential for many statistical analyses.
