totalstatistic
Totalstatistic (also written totalStatistic) is a term used in statistics and data analysis to denote an aggregate measure that summarizes multiple component statistics into a single value. There is no single universally accepted definition; meanings vary by discipline and application. In the most basic sense, totalstatistic can refer to the total sum of observed quantities across units, that is, total = sum_i x_i. In rate or probability contexts, it may refer to a pooled or weighted statistic such as a weighted average of component rates, where weights reflect sample sizes or relevance.
Calculation often depends on the purpose: for raw totals, simple summation suffices; for rates or proportions,
Applications include national statistics reporting (such as total population or total sales across regions), composite indices
Limitations include potential obscuration of distributional detail, susceptibility to Simpson's paradox, and sensitivity to chosen weights
