ANCOVA in Jamovi: Statistical Analysis and Covariance

Controlling for confounding variables is essential for extracting reliable insights from experimental and observational data. This text-based guide teaches you how to effectively conduct Analysis of Covariance (ANCOVA) using the open-source statistical tool Jamovi. You will build the skills needed to set up data, verify statistical assumptions, evaluate adjusted group differences, and interpret your output with confidence. What you'll learn: Understand core ANCOVA concepts, key terminology, and when covariance adjustment is necessary. Test critical assumptions including normality, homogeneity of variance, and homogeneity of regression slopes. Configure and run one-way and factorial ANCOVA models inside Jamovi. Calculate and interpret adjusted means, effect sizes, and pairwise post-hoc tests. Report statistical findings accurately according to standard research reporting guidelines. The course begins with foundational statistical definitions and model logic before walking you through hands-on data evaluation and interpretation workflows. This training is designed for students, researchers, and data practitioners who are new to ANCOVA or Jamovi and want a clear, step-by-step text resource.
