So I have just carried out an experiment, and have a set of values for x = [x1,x2,...] and y = [y1,y2...]. I have also calculated what sort of linear regression model they should follow (cartesian y = mx + c). Is there any way to plot my experimental points and compare them directly to the values of my theoretical regression model? Would I be able to get some sort of an r squared term & if so how? Would it even be a good idea to do so? I've been drawing blanks for quite some time towards how to do this, so any help would be greatly appreciated!
