Best Answer: It is possible for the standard deviation to be greater than the mean, even if all data points are positive numbers. However, the only way for this to happen is for most, if not all, data points to be at the extremes (with one extreme much greater in magnitude than the other) and nothing near the average.
The standard deviation is the square root of the variance, which in this case is or 1.73. Comparison to mean absolute deviation. The mean absolute deviation is when the negative sign is ignored so that all deviations are converted to positive numbers, summed, and then averaged.he standard deviation is the measure that is most often used to describe variability in data distributions. It can be thought of as a rough measure of the average amount by which observations deviate on either side of the mean.
