Learn how to perform a Hypothesis Test for the Regression Slope! 📈
In this video, we break down the logic behind testing if a linear relationship exists between two variables. We explore the null hypothesis for the population slope (β=0), understand the t-statistic formula t = b/SE(b), and visualize what the Standard Error really means.
Whether you are a student in AP Statistics or just brushing up on data analysis, this visual guide makes the concepts clear and easy to understand.
Topics Covered:
🔹 Linear Regression Basics
🔹 Null vs Alternative Hypotheses
🔹 The t-statistic formula
🔹 Degrees of Freedom (n-2)
🔹 Interpreting the results
