Press 'X' key to add X value. Press 'Y' key to add Y value. Press 'D' with the list key to delete from the list. Press 'R' with the list key to replace in the list. ============================================= *These instructions I recommend doing in this order* Press space key to get LSRL, and Correlation Coefficient. Press 'R' to get residuals. Press 'P' to get the residual plot, along with the full graph. ============================================= To see the values in variables and list, bring your mouse to the left side of the screen.
I used math noted in the project to get the result of these values. The equation for correlation coefficient is linked; r = ∑((x - x̄)(y - ȳ)) / sqrt(∑(x - x̄)² * ∑(y - ȳ)²) The grid can only be -180 to 180 by -240 by 240.
