Strengthen the methodological foundation of your quantitative research with our 1-day live online seminar on Sample Size Determination and Statistical Power Analysis, designed for PhD students, postdoctoral researchers, and academic staff who need rigorous, publishable justifications for sample size decisions. Led by Soleman Abu-Bader of the School of Social Work at Howard University, this hands-on workshop combines clear conceptual guidance with practical exercises in G*Power, covering a priori and post hoc power analysis, effect size selection, t-tests, ANOVA, regression, cluster and multilevel designs, attrition, sensitivity analysis, and publication-ready reporting for manuscripts and grant proposals. Participants will learn how to translate substantive hypotheses into defensible sample size calculations, produce reproducible input and annotated output, and strengthen the credibility of study designs, null results, and funding applications. The seminar is delivered live via Zoom, with recordings, slides, materials, and a monitored Q&A forum available for 30 days afterward, plus an official Instats certificate of completion. #SocialSciences #Education #Statistics #SocialWork #PublicHealth #DataScience #G*Power #SPSS #Research #ResearchTraining #Instats
