Regression and Correlation - Least squares regression - Correlation coefficient (r) - Interpreting residuals --- Sample Questions and Answers from the 2014 AP Statistics Multiple Choice Section While the full set of answers is extensive, here are representative examples that illustrate typical questions, solutions, and strategies. Question 1: Descriptive Statistics Q: The median of a data set is 50, and the data set contains 20 values. Which of the following could be the sum of all values in the data set? 10001. 9502. 10503. 11004. A: Since the median is 50, the 10th and 11th values (when ordered) are both 50 or close. The minimum total sum occurs when the lower 10 values are just below 50 and the upper 10 just above 50, but the median indicates the middle value(s). Assuming a symmetric distribution around 50, the sum would be approximately: - 20 × 50 = 1000 Correct 3 answer: 1000 Strategy: Recognize the median's position and approximate the sum accordingly. --- Question 2: Probability Q: A fair six-sided die is rolled twice.
