: back to [[Summary Statistics]] -- [[Statistical Theory]] '''Central tendency''' is the term statisticians use for any [[Statistic]] that you could quote as ''representative'' of an entire [[Data Set]]. The most commonly used measures of central tendency are the #[[Arithmetic Mean]], the sum of all data divided by the number of Observations in the [[Data Set]]]. #MediaN, the value that separates the highest half from the lowest half of the [[Data Set]]. #MoDe, the most common value in the [[Data Set]]. ---- [[Dick Beldin]]
