cohen_d_from_cohen_textbook

Calculates Cohen's d as described in Jacob Cohen's textbook (1988),
Statistical Power Analysis for the Behavioral Sciences, 2nd Edition
Cohen, J. (1988) tools:::Rd_expr_doi("10.4324/9780203771587")

A collection of functions for analyzing data typically collected
or used by behavioral scientists. Examples of the functions include
a function that compares groups in a factorial experimental design,
a function that conducts two-way analysis of variance (ANOVA),
and a function that cleans a data set generated by Qualtrics surveys.
Some of the functions will require installing additional package(s).
Such packages and other references are cited within the section
describing the relevant functions. Many functions in this package
rely heavily on these two popular R packages:
Dowle et al. (2021) <https://CRAN.R-project.org/package=data.table>.
Wickham et al. (2021) <https://CRAN.R-project.org/package=ggplot2>.
