<p>I remember taking the test in october, and there was a question about linear regression (there was a date table). Can anyone remember what we need to know about linear regression and how to solve those types of problems?</p>
<p>You use ti, plug in the list, then go on stat- calc- and press 3, then type in your explanatory then responsive variable, hit enter and you will get the slope, regression, standard deviation, and pretty much everything else.</p>
