Jaotustaristuses

Jaotustaristuses is an Estonian term used in statistics and data analysis to refer to the distributional attributes of a variable. The word is formed from jaotus, meaning distribution, and aristus (attribute or characteristic), reflecting its role in describing how data are spread or arranged.

In practice, jaotustaristused cover features of a data distribution such as location, dispersion, and shape. This includes classical descriptive statistics like mean, median, and mode (measures of central tendency), as well as dispersion measures such as variance and standard deviation. Higher-order descriptors—skewness and kurtosis—describe asymmetry and tail behavior. Percentiles, quartiles, and interquartile ranges express distributional position within a dataset. In applied contexts, jaotustaristused help compare distributions across groups, time periods, locations, or categories.

Usage extends beyond pure statistics. In fields such as ecology, economics, linguistics, and social sciences, the term can describe how observations are distributed across space, time, or categories, aiding interpretation of patterns, anomalies, and variability. Researchers often combine jaotustaristused with graphical tools (histograms, box plots, density plots) to convey the distributional profile of data.

Related concepts include jaotus (distribution), descriptive statistics, moments, and quantiles. While not a formal statistical method by itself, jaotustaristuses denotes the set of distribution-related characteristics used to summarize and compare data.
