===Descriptive statistics===
Frequentist approaches to descriptive statistics mostly involve averaging. For example, the mean of a sample is calculated as the total value of all observations divided by total number of observations, the standard deviation as the square root of the <math>1/N</math> times the mean<sup>2</sup>, and the standard error as the T* or Z* of the statistic times μ divided by the square root of N.
Frequentist approaches to descriptive statistics mostly involve averaging. For example, the mean of a sample is calculated as the total value of all observations divided by total number of observations, the standard deviation as <math> \sqrt (1/N)</math> times the square root of the mean<sup>2</sup>, and the standard error as the T* or Z* of the statistic times μ divided by the square root of N.
These methods stem from the view of data as ratios and probabilities.
