<p>Can someone please explain to me how to calculate regression? Thank you</p>
<p>Well if you have a TI 83 or 84 it’s really simple. Go to Stat->edit-> and then type your information for X into L1 an Y into L2. Then go to math->calc->linreg.
Hope I helped</p>
<p>but I have a casio graphing calculator…</p>
