Use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. It also produces the scatter plot with the line of best fit
Students can apply this concept to ANCOVA (analysis of covariance) to compare regression lines by testing the effect of a categorical value on a dependent variable.

The linear regression interpretation of the slope coefficient,m, is, "The estimated change in Y for a 1-unit increase of X." The interpretation of the intercept parameter,b, is, "The estimated value of Y when X equals 0." The first portion of results contains the best fit values of th...
