Interpretation of Standard Deviation

Standard Deviation shows how much variation or "dispersion" exists from the average (mean, or expected value). A low Standard Deviation indicates that the data points tend to be very close to the mean, whereas high Standard Deviation indicates that the data points are spread out over a large range of values.
