2. AP Statistics - Wikipedia

   en.wikipedia.org/wiki/AP_Statistics

   This offering is intended to imitate a one-semester, non-calculus based college statistics course, but high schools can decide to offer the course over one semester, two trimesters, or a full academic year. [2] The six-member AP Statistics Test Development Committee is responsible for developing the curriculum.

3. Advanced Placement exams - Wikipedia

   en.wikipedia.org/wiki/Advanced_Placement_exams

   Advanced Placement (AP) examinations are exams offered in United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...

4. Bootstrapping (statistics) - Wikipedia

   en.wikipedia.org/wiki/Bootstrapping_(statistics)

   The studentized test enjoys optimal properties as the statistic that is bootstrapped is pivotal (i.e. it does not depend on nuisance parameters as the t-test follows asymptotically a N(0,1) distribution), unlike the percentile bootstrap. Bias-corrected bootstrap – adjusts for bias in the bootstrap distribution.

5. Replication (statistics) - Wikipedia

   en.wikipedia.org/wiki/Replication_(statistics)

   In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [1]

6. Bias (statistics) - Wikipedia

   en.wikipedia.org/wiki/Bias_(statistics)

   In educational measurement, bias is defined as "Systematic errors in test content, test administration, and/or scoring procedures that can cause some test takers to get either lower or higher scores than their true ability would merit." [16] The source of the bias is irrelevant to the trait the test is intended to measure.

7. AP World History: Modern - Wikipedia

   en.wikipedia.org/wiki/AP_World_History:_Modern

   In 2012, the head of AP Grading, Trevor Packer, stated that the reason for the low percentages of 5s is that "AP World History is a college-level course, & many sophomores aren't yet writing at that level." 10.44 percent of all seniors who took the exam in 2012 received a 5, while just 6.62 percent of sophomores received a 5.

8. AP Calculus - Wikipedia

   en.wikipedia.org/wiki/AP_Calculus

   It can be seen from the tables that the pass rate (score of 3 or higher) of AP Calculus BC is higher than AP Calculus AB. It can also be noted that about 1/3 as many take the BC exam as take the AB exam. A possible explanation for the higher scores on BC is that students who take AP Calculus BC are more prepared and advanced in math.

9. Rule of three (statistics) - Wikipedia

   en.wikipedia.org/wiki/Rule_of_three_(statistics)

   In statistical analysis, the rule of three states that if a certain event did not occur in a sample with n subjects, the interval from 0 to 3/ n is a 95% confidence interval for the rate of occurrences in the population. When n is greater than 30, this is a good approximation of results from more sensitive tests.
