AP® Statistics Syllabus
Course Design
AP Statistics is a course instructed through discovery and technology to develop a broad understanding and
connection among four major fundamental concepts: experimental design, exploration and presentation of data,
anticipated patterns, and drawing conclusions through the process of inferential statistics. It is important to note that
the course will provide a careful balance between the use of technology and written expression. By the beginning of
the month of May, students should be prepared to take and pass the AP Statistics exam.

Technology
All students are required to own and use a Texas Instruments TI-83, TI-83 plus or a TI-84 graphing calculator. An
instructor’s TI-83 plus overhead projection unit is used in the classroom to supplement calculator instruction.
All students are required to use Minitab for Windows statistical software. This software package is owned by our
school and can be used in any of our four computer laboratories. For three weeks following the AP Statistics exam,
students are required to produce a major statistical project using both Minitab and Microsoft Word.
The internet is used to great extent in this course as a data resource. Students are asked to find relevant data for
statistical applications on an ongoing basis.
Course Outline
The course is organized through the chapters in the primary textbook. Each Friday and the entire three weeks
following the AP exam, the course meets in the computer lab to work on a statistical project using Minitab statistical
software.

Statistical Inference:
 Special case of normally distributed data

regression line)
includes a theme and

tendency with written descriptions;
graphical representations using all data
collected (at least five different graphs)
with written interpretations; linear
regression (if applicable); numerical and/or
categorical hypothesis testing that includes
a confidence interval; a conclusion that
draws all aspects of the statistical process,
including but not limited to design,
analysis and conclusions.
Assessment
Tests are given at the completion of each chapter/unit. Quizzes are usually given weekly. Homework is assigned
and collected each Monday as a weekly packet. Computer assignments are graded as quizzes with the exception of
the final project, which is a test grade.
Most tests are designed to closely follow the AP exam format: 50% multiple-choice, 50% free response and always
valued at 100 points. Quizzes are smaller in scope than tests: one or two free response questions or a classroom
simulation ranging from 10 to 25 points. Homework is assigned from each section of the textbook with
approximately 20 to 30 problems assigned per week. Homework is assessed using a 3 point rubric.
On a daily basis, students are encouraged to effectively communicate relationships among statistical methods,
results and conclusions in a written format. Often students are asked “how” or “why” when explaining the nature of
data. A strong emphasis is placed on the appropriate use of statistical vocabulary when validating hypotheses.
Moreover, reinforcement is placed on neat and organized written and graphical work. They are required to draw
connections of their statistical knowledge in situational context (often in-class simulations) from design to numerical
and graphical interpretation to analysis and conclusion using complete, grammatically correct sentences. The
purpose of the spring statistics project is to draw these connections together from a unique data set determined and
collected by each student. The project requires students to validate statistical relationships through written
expression from experimental design to conclusion.
In class, we often use statistical simulations that provide students with “hands on” experiences.
Simulations range from simple in-class surveys to marble and dice games to a 100 penny project to sampling
Goldfish crackers. With all simulations, students are asked to discover the true nature between the data used and the
conclusions that can be drawn from the design and summary of data.
