I'm trying to calculate the sum of squared errors on my ti-84plus calculator, after I've successful entered the residuals in L3,I go to calc ---> 1.) 1-Var Stats, and it should allow me toselect which List (ex: L1, L2, L3, etc) to make calculations from,but instead when I hit enter after hitting variable stats, its justblank and won't allow me to select a list and it calculates justList 1 I'm pretty sure. How do I allow my calc to let me inputwhich list I want it to calculate after hitting VariableStats?
