===Univariate analysis===
[[Univariate analysis]] involves describing the [[Frequency distribution|distribution]] of a single variable, including its central tendency (including the [[mean]], [[median]], and [[Mode (statistics)|mode]]) and dispersion (including the [[range (statistics)|range]] and [[quartiles]] of the data-set, and measures of spread such as the [[variance]] and [[standard deviation]]). The shape of the distribution may also be described via indices such as [[skewness]] and [[kurtosis]]. Characteristics of a variable's distribution may also be depicted in graphical or tabular format, including [[histograms]] and [[stem-and-leaf display]].
