Advanced Placement Statistics (AP Statistics or AP Stats) is an upper level high school mathematics course offered by the College Board that, upon successful completion, will provide college credit or higher college course placement for the student. This course is equivalent to a non-calculus-based introductory college statistics course. However, there are schools that are able to integrate AP Calculus BC into this course.
One of the College Board's more recent offerings, the first AP Statistics exam was administered in May 1997. It has set records for the fastest growing AP course. Many competitive colleges encourage students to take AP Statistics during their senior year.

[edit] The exam
The AP Statistics exam is three hours long with 90 minutes on each of its two sections: Multiple Choice and Free-Response. The multiple choice portion of the exam is graded with 0 points for blank answers, -1/4 points for incorrect answers, and +1 point for correct answers. The free response section contains five questions and one investigative task. Questions typically relate two or more areas of study (such as probability and statistical inference), while the investigative task requires the integration and appliance of several statistical concepts. The multiple choice and free response sections each count equally towards the final grade. Each student is expected to bring an approved graphing calculator to the exam, and the calculator may be used for the entire exam.
[edit] Grade distributions
In the 2007 administration, 98,023 students took the exam from 4,824 schools. The mean score was a 2.80.
The grade distribution for 2007 was:
| Score | Percent |
|---|---|
| 5 | 11.9% |
| 4 | 21.5% |
| 3 | 25.4% |
| 2 | 17.1% |
| 1 | 24.1% |
