    Properties of standard deviation

    Standard deviation is only used to measure spread or dispersion around the mean of a data set. Standard deviation is never negative. Standard deviation is sensitive to outliers. … For data with approximately the same mean, the greater the spread, the greater the standard deviation

    Standard Deviation introduces two important things, The Normal Curve (shown below) and the 68/95/99.7 Rule. … Standard deviation is considered the most useful index of variability. It is a single number that tells us the variability, or spread, of a distribution (group of scores)
