Mastering Correlation & Regression Analysis by Hand: Researcher’s Insight and Edu Hypo Explained

Mastering Correlation & Regression Analysis by Hand: Researcher’s Insight and Educational Hypotheses Explained Unlock the power of Correlation and Regression Analysis—without relying on computers, calculators, or statistical software. In this lesson, your professor of statistics and education walks you step-by-step through the principles, formulas, and logical foundations behind two of the most essential tools in quantitative research. Whether you are a student, educator, or emerging researcher, this video will help you understand not just how to compute these statistics manually, but also why they matter in real-world educational research. 🔍 What You Will Learn What correlation really measures in human behavior and educational outcomes Difference between positive, negative, and zero correlations The educational meaning behind strong vs. weak relationships How to compute Pearson’s r manually using raw scores and deviation scores How to formulate and test basic educational hypotheses using hand-worked correlation How simple linear regression works conceptually Step-by-step manual calculations for: Regression slope (b) Intercept (a) Regression equation (Ŷ = a + bX) Making predictions without a computer How researchers interpret results in theses, dissertations, and journal articles 📘 Researcher’s Insight Section Includes Why correlation does not imply causation (with education-specific examples) Pitfalls in interpreting regression in classroom or school-based data How to write hypotheses such as: “There is a significant relationship between students’ study habits and their mathematics achievement.” “Teacher motivation predicts learner engagement in secondary schools.” ✏️ Manual Calculation Focus No SPSS. No Excel. No R. Just pure reasoning, formulas, and researcher logic. Perfect for students preparing for exams, researchers defending methodology, or anyone wanting a deeper conceptual grasp of educational statistics. 🎙️ New to streaming or looking to level up?
