In plot setup, go to the y box and define it as resid, you can get resid by pressing 2ND VAR LINK which is the minus button and selecting resid which is in the STATVARS subfolder. You need to find the regression equation on the calculator first so it has the residual values stored before graphing a residual plot.

The things that a certain someone does at school:
-Steals peoples Accounting Checkpoints, cuts out the notes and returns the book minus the notes.
-Steals teacher resources which are intended for the whole class.
-Steals peoples Accounting notes that they write in class.
-Gets trial exams off VCEnotes before doing them at school so he boast about his 'intelligence'.
-Tells people that a revision lecture is fully booked out when it is not.
-Claims that friends give him notes and summaries which have actually been downloaded off VCEnotes.
