About

This AP Statistics quiz focuses comprehensively on linear regression analysis, targeting Grade 12 students enrolled in Advanced Placement Statistics. The questions assess critical understanding of correlation coefficients, least squares regression lines, residual analysis, coefficient of determination (r²), data transformations for exponential relationships, and the identification of influential points and outliers. Students must demonstrate mastery of interpreting regression output, calculating residuals using the formula (observed - predicted), distinguishing between interpolation and extrapolation, understanding the properties of correlation (including unit invariance), and analyzing scatter plots and residual plots to evaluate model fit. The quiz requires students to work with real-world contexts involving biological measurements, nutritional data, and environmental science, demanding both computational skills and conceptual understanding of when linear models are appropriate and how various data points affect regression analysis. Created by Mike Trejo, a Mathematics teacher in US who teaches grade 12. This comprehensive review quiz serves multiple instructional purposes in AP Statistics classrooms, functioning effectively as a summative review before major assessments, targeted practice for students struggling with regression concepts, or structured homework to reinforce classroom learning. The quiz excellently supports formative assessment by revealing specific gaps in student understanding of regression analysis through its diverse question formats and real-world applications. Teachers can use individual questions as warm-up problems or discussion starters, while the complete quiz provides comprehensive preparation for AP Statistics exam regression questions. This assessment aligns with Common Core Standards S-ID.6 (representing data on two quantitative variables and summarizing relationships), S-ID.7 (interpreting slope and intercept of linear fits), and S-ID.8 (computing and interpreting correlation coefficients for linear fits), while directly supporting AP Statistics Learning Objectives related to exploring bivariate data and performing statistical inference.

Which of the following statements is not true of the correlation r between the lengths in inches and weights in pounds of a sample of brook trout?

r must take a value between -1 and 1.

r is measured in inches.

If longer trout tend to also be heavier, then r>0.

r would not change if we measured the lengths of the trout in centimeters instead of inches.

Write the linear regression equation for the data set foot length (x) and height (y).

yhat = 28.93 + 1.155x
height = 28.39(foot length) + 1.155
yhat = 1.878 + 117.99x
height = 117.99 + 1.878(foot length)
