This tutorial by Dr. Goli Sadri covers essential concepts in research design within organizational behavior. It outlines the key variables: independent variables (causal), dependent variables (affected), and moderator variables (influence relationships). The process of collecting data through surveys and questionnaires is introduced, along with the subsequent analysis methods, including descriptive statistics, t-tests, ANOVA, correlation, and multiple regression. This guide helps researchers clarify their hypotheses and understand the relationships among variables.
