Simple regression is a statistical method used to model the relationship between a dependent variable (y) and a single independent variable (x). It helps predict the value of y based on x. Assumptions 1.Linearity – The relationship between x and y is linear. 2. Independence – Observations are independent of each other. 3. Homoscedasticity – The variance of residuals (errors) is constant. 4. Normality of Residuals – The residuals follow a normal distribution. 5. No Multicollinearity – Only one independent variable is used. Steps in Hypothesis Testing Formula
