Formulas for the sampling distributions have been moved to Section III. There will not be an Investigative Task on the 2020 AP Statistics Exam. Helping math teachers bring statistics to life. Most of the formulas in this section have been arranged in a table. This is all fine and dandy, but the experienced AP Stats teachers knew what else was coming: Check out this video that walks students through every single formula on the new formula page.

If you are an experienced AP Statistics teacher, you might want to know exactly what is different about this new formula sheet as compared to the previous version. The formula for the pooled standard deviation is no longer included. As on a traditional AP Exam, students may require access to the AP Statistics Formula Sheet and Tables (.pdf Important Concepts not on the AP Statistics Formula Sheet Part I: IQR = Q 3 – Q 1 Test for an outlier: 1.5(IQR) above Q 3 or below Q 1 The calculator will run the test for you as long as you choose the boxplot with the oulier on it in STATPLOT Linear transformation: Addition: affects center NOT spread adds to , M, Q 1 , Q 3, IQR not σ In short, we almost always use the standard error because we are using data from the sample(s) to estimate variability. The equation of the least-squares regression line is now in y = a + bx (as it should be), rather than the y = b0 + b1x form. Check out this video that walks students through every single formula on the new formula page. Due to the COVID outbreak, the 2020 exam only covers ap stats units 1-7. Note the new formulas below the standard error of the slope, which include the formula for the standard deviation of the residuals s and the standard deviation of x, sx. 2020 AP Test Changes Due to COVID-19. AP Statistics Student Resource Packet The fol lowing formula s and tables are similar t o the ones which wil l be pro vided t o you on the A dvanc ed Plac ement Exam. The 2020 AP Stats exam is on. Hooray! The formulas for binomial and geometric probability in the new formula sheet use P(X=x) instead of P(X=k) and replace all instances of k with x. All AP Tests. In the P(X=x) notation, upper case X represents the random variable and lower case x represents a particular value of the random variable.

If we happen to know the standard deviation of the sampling distribution (like in the one-sample z test for p), use the standard deviation, not the standard error.
