    Is linear regression calculated by creating a guess equation y=ax+b with the experimental constants inserted? @hartnn

    my measured slope is 0.5545 and the calculated predictions slope is 0.5600 I don't need to calculate the linear regression, I just want to understand what it is

    I believe linear regression is about: Sum of (the distance from data points to fit line)^2

    Now how does that relate to the the y=ax+b equation?

    oh it's the average distance of all of those points from the predicted line
