Summary

The 2018 AP Statistics scoring guidelines for Question 2 assess a student's ability to calculate sample size, explain bias in a survey, and estimate a proportion. The question has three parts: (a) calculating sample size using a confidence interval, (b) explaining bias in a survey method, and (c) estimating a proportion from sample data. Each part is scored as essentially correct, partially correct, or incorrect based on specific components. For part (a), the student must use the standard error formula, show evidence of correct calculations, and provide a single whole-number answer. For part (b), the student must explain why responses might differ from the truth, how responses might differ, and the effect of bias on the point estimate. For part (c), the student must provide a correct answer for the expected number of students and estimate the proportion of students who would respond yes to the question.
