so i just saw the topic regressions mentioned on the collegeboard website in the math2 “topics covered on this test” section…i dont see it in any of the books i have(PR and barrons).
is it there on the test because the formulas are pretty long
I vaguely remember one question on Math II that asked us to plot a linear regression and do some stuff with it, but nothing really algebra-heavy (such as deriving the formula for the least-squares regression line, which we did in multi-variable calculus). You might want to just familiarize yourself with what it is, and what the line and slope represent.
you can do regression on a ti84… just search it up on google. i dont think i knew how to do regression when I took the exam (i just knew how to do it on a ti84) and I got a 780.
