Casio fx ES Plus - Simple Linear Regression Sums, Intercept, Slope, Correlation, Determination, ŷ

Learn how to perform simple linear regression on the Casio fx ES Plus series calculator. In this step by step tutorial, we’ll enter data, generate sums, and calculate the regression intercept, slope, and correlation coefficient (r). You’ll also see how to interpret the regression equation and determine (R²) to measure how well the model explains variation in the data.
