Abstract
In psychological science, rigorous research methods and robust statistical techniques form the twin pillars of valid and credible knowledge. This paper presents an integrative overview of how researchers can master both research design and statistical analysis in psychology. It outlines key methodological principlesincluding measurement, design, sampling, ethicsas well as core statistical tools and how they interrelate with psychological inquiry. Illustrative examples highlight how method and statistics cooperate, and a discussion addresses contemporary challenges (e.g., replicability, effect size, open science). The aim is to provide a roadmap for psychologists (students, practitioners, investigators) to elevate their competence in research and statistics, thereby enhancing the quality of psychological investigation.
