Description
To center a variable in regression means to set its value at zero and interpret all other values in relation to this reference point. Regarding race and gender, researchers often center male and White at zero. Further, it is typical that research vignettes in statistics textbooks are similarly seated in a White, Western (frequently U.S.), heteronormative, framework. ReCentering Psych Stats seeks to provide statistics training for psychology students (undergraduate, graduate, and post-doctoral) in a socially and culturally responsive way. All lessons use the open-source statistics program, R (and its associated packages). Each chapter includes a screencast lesson, features a workflow for statistical decision-making, and includes all R code necessary for conducting the statistic. Research vignettes are drawn from the published psychology literature. When possible, these articles are authored by individuals who hold identities that have been marginalized in the scientific literature; correctly use the statistic that is taught in the lesson; and focus on issues of justice, equity, inclusion, and diversity. When possible, lessons include interviews with researchers from the featured vignettes. Each chapter includes suggestions for practice that are graded in complexity, such that learners can choose the degree of challenge. In this base volume, chapters include an orientation to the R environment and statistics lessons include coverage of inferential statistics (i.e., descriptive statistics, t-tests [one-way, paired, independent]) and analysis of variance (i.e., one-way, factorial, repeated measures, mixed design, ANCOVA). Each lesson includes a power analysis and attention to Type I error. Lessons on correlation and multiple regression are forthcoming. Additional volumes of ReCentering Psych Stats include Psychometrics and Multivariate Modeling. ReCentering Psych Stats is perpetually-in-progress; suggestions for corrections or chapters are welcome: recenterpsychstats@gmail.com

She is authoring the open educational resource, ReCentering Psych Stats, as a socially responsive pedagogy in statistics/research methods training. Her research interests fall at the intersections of vocational, global, and sustainable psychology – with particular interests in plotting longitudinal growth trajectories examining the simultaneous effects of individual and contextual factors. Significant research projects have explored global learning outcomes in returnees from study abroad; career development in response to an online, calling-infused intervention; and wearing facemasks during the pandemic. Dr. Bikos has served on a number of editorial boards including the Journal of Vocational Behavior, Career Development Quarterly, Journal of Counseling Psychology, and Journal of Career Development.
