For a given series of data, statistics aims at analysis and drawing conclusions. The various measures of central tendency – mean, median and mode represent the values in a series. However, we can further implement this analytical claim of statistics, by measuring the scattering and dispersion of data around these measures of central tendency.For example, the range, in a series of men distributed by their ages, gives us an idea of how much the ages can vary from the central value. So without f...

### 2. Mean and standard deviation | The BMJ

The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently the squares of the differences are added. The sum of the squares is then divided by the number of observations minus oneto give the mean of the squares, and the square root is taken to bring the measurements back to the units we started with. (The division by t...
