Parts (a), (b), and (c) are scored as essentially correct (E), partially correct (P), or incorrect (I).
is scored as follows: Essentially correct (E) if the response correctly describes three aspects of association: direction (positive), strength (weak or moderate), and form (curved or nonlinear), AND describes the association in context. Partially correct (P) if the response correctly describes two aspects of association in context OR if the respons...
is scored as follows: Essentially correct (E) if the response identifies the correct point with reasonable approximations to the price and quality values AND gives either of the following two explanations: The point in conjunction with the entire collection of points appears to have a curved (or nonlinear) form. A linear model that includes all the...
Two parts essentially correct and one part partially correct
Two parts essentially correct and one part incorrect OR One part essentially correct and two parts partially correct OR One part essentially correct and one part partially correct (BUT see the exception noted with an asterisk below) OR All three parts partially correct
One part essentially correct and two parts incorrect OR *Part (c) essentially correct, part (b) partially correct, and part (a) incorrect OR Two parts partially correct and one part incorrect
is scored as follows: Essentially correct (E) if all three probabilities are filled in correctly in the table in part (a) AND the expected value is calculated correctly in part (b), with work shown. Partially correct (P) if all three probabilities are filled in correctly in the table in part (a) AND the expected value is not calculated correctly in...
Two sections essentially correct and one section partially correct
Two sections essentially correct and one section incorrect OR One section essentially correct and one or two sections partially correct OR Three sections partially correct
One section essentially correct and two sections incorrect OR Two sections partially correct and one section incorrect
is scored as follows: Essentially correct (E) if the response correctly compares center (or location) for both distributions. Incorrect (I) otherwise.
is scored as follows: Essentially correct (E) if the response correctly compares variability for both distributions. Incorrect (I) otherwise.
is scored as follows: Essentially correct (E) if the response includes context related to the variable of interest (household size) AND the response correctly identifies the shapes of both distributions. Partially correct (P) if the response correctly identifies the shapes of both distributions BUT does NOT include context related to the variable o...
is scored as follows: Essentially correct (E) if the response correctly includes the following three components: Identifies the correct test procedure (by name or by formula). Checks for randomness. Checks for normality. Partially correct (P) if the response correctly includes two of the three components listed above. Incorrect (I) if the respons...
is scored as follows: Essentially correct (E) if the response correctly calculates both the test statistic and a p-value that is consistent with the stated alternative hypothesis. Partially correct (P) if the response correctly calculates the test statistic but not the p-value, OR if the response calculates the test statistic incorrectly but then c...
This is not a randomly selected sample because the sample was selected by recruiting volunteers. It seems reasonable to think that volunteers would be more physically fit than the population of city adults as a whole. Therefore, the sample proportion will likely overestimate the population proportion of adult residents in the city who are able to p...
Parts (a), (b), and (c) are scored as essentially correct (E), partially correct (P), or incorrect (I).
is scored as follows: Essentially correct (E) if the response correctly completes the following two components: Describes the error in context by referring to the proportion of adult residents in the city who are able to pass the physical fitness test. Describes the consequence as not funding the program and/or continuing poor physical fitness of t...
is scored as follows: Essentially correct (E) if the response correctly completes the following three components: States that the sample is not random and/or says that volunteers were used. Describes how the sample is “different” with regard to physical fitness or another variable related to the ability to pass the physical fitness test. Addresses ...

The comparative dotplots from Rania’s data reveal that the distribution of the number of soft drinks for females appears to be quite different from that of males. In particular, the centers of the distributions appear to be significantly different. Additionally, the variability of values around the center within gender in each of Rania’s dotplots a...
Parts (a), (b), (c), and (d) are scored as essentially correct (E), partially correct (P), or incorrect (I).
is scored as follows: Essentially correct (E) if a reasonable justification is provided based on BOTH of the following two components: Smaller variability in responses for each gender in comparison with the variability in responses in Peter’s data, and Linkage (either explicit or implicit) between the smaller variability in responses for each gende...

Feb 6, 2024 · The College Board has released two full AP® Statistics Exams: 2012 AP® Statistics Exam and 1997 AP® Statistics Exam. Because they often reuse multiple choice questions, they limit the number of full official tests they make public (you can supplement this with full-length practice exams from Albert).
See how all students performed on past AP Statistics exams. The official score distribution table on this page shows the percentages of 1s, 2s, 3s, 4s, and 5s, 3+, total test takers and mean score for each year that data is available.
AP Statistics is an introductory college-level statistics course that introduces students to the major concepts and tools for collecting, analyzing, and drawing conclusions from data. Students cultivate their understanding of statistics using technology, investigations, problem solving, and writing as they explore concepts like variation and ...
Apr 3, 2023 · The AP Statistics exam tests your mastery of the four basic themes of statistics—exploratory analysis, planning and conducting a study, probability, and statistical inference. The College Board provides a content breakdown that is helpful when deciding where to focus your energy during test prep.
