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.
In this case it is 0.3905 pounds. In brief: â¢ Both variance and standard deviation are measures of spread of values in any data. â¢ Variance is calculated by taking the mean of the squares of individual differences from the mean of the sample.â¢ Standard deviation is the square root of the variance.n this case it is 0.3905 pounds.
