For example, the spread of marks in a mathematics exam is often much wider than in English. In other data sets, the data values are more widely spread out around the mean. In a set of data, the range is the difference between the greatest and smallest value. One minute of angle is equal to about 1 inch of spread at 100 yards (technically 1.047 at 100, but 1 inch is easier to keep in your head.) Standard deviation calculates the extent to which the values differ from the average. Statistics. Functions can be used to create formulas that manipulate data and calculate strings and numbers. The other measures are the mode (value with greatest frequency) and the median (middle of the ordered set). Small standard deviations mean that most of your data is clustered around the mean. Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance. It is so common in fact, that most people simply refer to the concept of “spread” as “variance.”.
