Statistical Calculations

Statistical Calculations

Branch of applied mathematics based on experimental observations from which we establish plausible hypotheses that allow for predictions about analogous circumstances.


Consider the following observations of precipitation recorded during one week, in millimetres of rain:

E = {1, 4, 12, 8, 0, 7, 3}

The mean of this precipitation is: \(\overline{x}=\frac{1\space +\space 4\space +\space 12\space +\space 8\space +\space 0\space +\space 7\space +\space 3}{7}\) = \(\frac{35}{5}\) = 5.

Calculating the mean of a set of data is a statistical calculation.
