| standard deviation |
s). A measure of the "spread" of the normal distribution curve for a given data set. It is one of two parameters for the normal curve; the other is the mean. It is always symbolized by a lower-case Greek sigma (s). The standard deviation of the population itself is the square root of the sum of the squares of the differences between each data value and the mean (m) of all the data values, divided by their number (n). As a formula,

| standard deviation |
The standard deviation (s or s) is defined as the positive square root of the variance. The variance is a measure in squared units and has little meaning with respect to the data. Thus, the standard deviation is a measure of variability expressed in the same units as the data. The standard deviation is very much like a mean or an "average" of these deviations. ...

| standard deviation |
A measure of the variability of a distribution of scores. The more the scores cluster around the mean, the smaller the standard deviation. In a normal distribution, 68% of the scores fall within one standard deviation above and one standard deviation below the mean.
