Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
I teach high school physics, and students are graping and conducting a LinReg for a set of data stored in lists (e.g. LinReg L3, L2, Y1).
No problem with this, it works great, but one student was getting different values for a, b, r2, r. I checked her lists, and they were all correct. I even tried re-entering all the data, but still got the same results.
I finally cleared the RAM ([MEM] RESET ... All RAM, and now we are getting the right answer.
Any ideas of what might have been wrong?
Probly because the calc was miscalibrated or someone screwed around with the variables...
hope this helps
