“…Therefore, many such studies will be anticonservative and overestimate the importance of between-variety differences. In addition, virtually none of the studies that use frequencies or frequency differences of features Y to make a theoretical point consider the dispersion of Y in the corpus although it has been shown that underdispersion can invalidate any corpus statistic (Gries, 2008(Gries, , 2020.…”

“…Dispersion (Gries, 2008(Gries, , 2020(Gries, , 2021 measures how equally widespread a given ABB word is across all three corpus data types, and can be viewed as a sort of correction on raw frequencies. For instance, do some words only appear in the institutionalized dictionary data or are they used relatively equally in social media data and traditional corpus material as well?…”

“…The scores given above are the result of partitioning COCA into 100 parts, and so it may be that a term like "justify" or "know" is in fact quite unevenly distributed but that this is not reflected by the score. Biber et al (2016) recommend instead using Gries' DP (Gries 2008(Gries , 2019 and Gries himself has made this score (and a range of other dispersion scores) available for all word forms in the BNC. 14 Gries' DP (with a lower score indicating that the term is more widely distributed) for the various word forms for "justify" and "know" are shown in Table 2.…”
