In this video, I demonstrate how to use ClassCalc to find the linear regression equation (aka the line of best fit) and the correlation coefficient. The process for doing hand calculations is very lengthy and time consuming, so using technology will speed the process up for you. I will also demonstrate how to use the equation to make predictions. ClassCalc is a free online graphing calculator: https://classcalc.com/graphing-calcul.... There is also a free app for your smart phone or tablet.
