What does statistically mean?
“Statistically” means in a way that relies on statistics, numerical evidence, or the methods of statistical analysis. It is commonly used when describing results from research, comparing groups, evaluating probabilities, or determining whether an observed difference is likely to be more than ordinary chance. For example, a finding may be described as “statistically significant” when it meets the criteria established by a statistical test. This does not necessarily mean that the finding is large, important, or practically useful; statistical significance and practical significance are distinct ideas. In everyday discussion, the adverb can also mean “according to the available figures,” as in “Statistically, the city has grown rapidly.” The word is formal and technical, although it is widely understood and used outside specialist settings.

Where does statistically come from?
“Statistically” was formed from “statistic” with the adverbial suffix “-ally.” The root ultimately comes through Latin from Greek statistikos, “pertaining to statistics” or “skilled in statistics,” which was derived from statistes, “one who collects or knows statistics,” itself connected with Greek statos, “standing.” The family later developed forms such as “statistic,” “statistical,” “statistician,” and “statistics.”
