How to fill out linear regression for bivariate

How to fill out linear regression for bivariate?

1. Collect a dataset consisting of paired values for two variables, typically denoted as X and Y.
2. Plot the data points on a scatter plot to visualize the relationship between the variables.
3. Calculate the means (average) of both X and Y values.
4. Calculate the covariance between X and Y using the formula: Cov(X, Y) = Σ((X - X_mean) * (Y - Y_mean)) / (n-1), where n is the number of data points.
5. Calculate the variance of X using the formula: Var(X) = Σ((X - X_mean) * (X - X_mean)) / (n-1).
6. Calculate the variance of Y using the formula: Var(Y) = Σ((Y - Y_mean) * (Y - Y_mean)) / (n-1).
7. Calculate the regression coefficient (slope) using the formula: β = Cov(X, Y) / Var(X).
8. Calculate the intercept using the formula: α = Y_mean - β * X_mean.
9. The linear regression model is now represented as Y = α + βX.
