## Uncertainty In Slope Of Best Fit Line

a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top How is the formula for the Standard error of the slope in linear regression derived? [duplicate] up vote 3 down vote favorite This question already has an answer here: Derive Variance of regression coefficient slope uncertainty calculator in simple linear regression 2 answers As stated in many textbooks, the Standard error of the slope in linear regression with one variable is $\sqrt{\frac{s^2}{SSX}}$ or some rewrite, ${s^2}$ being the error variance and ${SSX}$ being the sum of the ${x}$-squares. Can anybody help with an explicit proof? regression standard-error share|improve this question edited Apr 14 '14 at 7:05 asked Mar 28 '14 at 20:11 user3451767 11319 marked as duplicate by gung, Nick Stauner, Momo, COOLSerdash, Glen_b♦ Mar 29 '14 at 8:00 This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. 1 see stats.stackexchange.com/questions/88461/… –TooTone Mar 28 '14 at 23:19 It's reasonably straightforward if you start from the fact that the line goes through $(\bar x,\bar y)$ and write the slope estimator as a kind of average. –Glen_b♦ Mar 29 '14 at 0:01 Thx.

The smaller the "s" value, the closer your values are to the regression line. Standard error of regression slope is a term you're likely to come across in AP Statistics. In http://www.statisticshowto.com/find-standard-error-regression-slope/ fact, you'll find the formula on the AP statistics formulas list given to you on the day of the exam. Standard Error of Regression Slope Formula SE of regression slope = sb1 = sqrt [ Σ(yi - ŷi)2 / (n - 2) ] / sqrt [ Σ(xi - x)2 ]). The equation looks a little ugly, but the secret is you won't need to work the formula by hand on the test. Even if you think you know how to use the formula, it's so time-consuming to work that you'll waste about 20-30 minutes on one question if you try to do the calculations by hand! The TI-83 calculator is allowed in the test and it can help you find the standard error of regression slope. Note: The TI83 doesn't find the SE of the regression slope directly; the "s" reported on the output is the SE of the residuals, not the SE of the regression slope. However, you can use the output to find it with a simple division. Step 1: Enter your data into lists L1 and L2. If you don't know how to enter data into a list, see:TI-83 Scatter Plot.) Step 2: Press STAT, scroll right to TESTS and then select E:LinRegTTest Step 3
