Question about Texas Instruments TI-84 Plus Calculator
Ok I have a fairly new TI-84 Plus graphing calculator and I've been using scatter plots and finding the "line of best fit" (Linear Regression). I would plot the points and push [STAT] then over to the [CALC] menu and go down to [LinReg (ax+b)] and I would push [ENTER] to get the values for a and b. This has worked in the past. Now, I tried and I get "ERR:DIM MISMATCH" when I push [ENTER] after having "LinReg (ax+b)" appear on my screen. Why is this happening and how can I fix it? Please help!
Some old configuration settings, or old variables are spoiling your fun. Clear the RAM and start again.
Hope it helps.
