AP® Statistics involves the study of four main areas: exploratory analysis; planning a
study; probability; and statistical inference. According to the College Board, upon
entering this course students are expected to have mathematical maturity and quantitative
reasoning ability. Mathematical maturity could be defined as a complete working
knowledge of the graphical and algebraic concepts through Math Analysis, including
linear, quadratic, exponential, and logarithmic functions.
In contrast to many math classes, this course will require reading of the text.
This AP Statistics course is taught as an activity-based course in which students actively
construct their own understanding of the concepts and techniques of statistics.
Textbook: Bock, David E., Paul F. Velleman, and Richard D. De Veaux. 2010. Stats:
Modeling the World: 3rd Edition. Addison-Wesley.
Calculator: A TI-83 or TI-84 is required for successful completion of this course.
Technology is incorporated throughout the text, including the use of graphing calculators.
Each chapter in the text has a section on calculator use to give the student instruction and
practice with the statistical capabilities of the calculator. The calculator is used
throughout the course to:
- Display graphs, histograms, and various types of plots
- Generate simulation and probability data
- Analyze univariate and bi-variate data through t-tests, measures of central
tendency, regression, and chi-square analysis
Where necessary, students will use Excel or be given access to appropriate data reports
for interpretation.
Internet access is required for successful completion of this course. Assignments will be
posted on Edmodo. An Edmodo account is required.
Grades
- Practice (20%)
o Problem sets will be assigned throughout the course.
o Group quizzes: students will work on a research-based problem that
applies statistical concepts learned in class to real data.
- Performance (20%)
o Article Review: Each quarter, individual students will locate a news story
or study that applies statistics. Students will:
 Briefly summarize the content of the article and purpose of the
study.

-
Describe the methodology applied in the study. This includes
sample sizes and statistical tests used.
 Critique the methods and offer at least one question for future
research.
o Unit Projects: For each unit, groups of students will collect and analyze
data using one of the methods discussed in the unit. All are group graded.
Reports will include:
 Answering the questions of who, what, when, where, why, and
how about the data.
 The question to be answered.
 A description of the method of analysis or display used, including
a list of the assumptions applicable to the model.
 An appropriate tabular, graphical, or data display from a statistics
program such as SPSS or a spreadsheet program such as Excel.
 A brief discussion of the results, including statistical inferences
and observations about the data.
o Individual Project: Each semester, students will complete one project that
applies statistical concepts from class. The first semester project is
outlined here. During the second semester, the project requires students to
design surveys or experiments, gather data, anticipate sources of bias or
confounding variables, analyze the data numerically and graphically, and
apply inferential statistics to draw conclusions for a population. Students
write formal reports on their projects using statistical language and present
their findings to the class through a poster and oral presentation. The first
semester project can be found at the end of this syllabus.
Measurement (60%)
o Unit Tests. Each unit test is cumulative. Measurement grades are based
on the average of all unit test scores or the most recent test score,
whichever is greater.
Attendance and tardiness: Regular, on-time class attendance is expected. Failure to get
an absence cleared may result in the loss of credit for the class. If you are placed on
attendance probation, expect to lose credit.
Late work: In general, late work is not accepted unless you were excused the day it was
due (and in accordance with district and school policy). Ignorance is not a legitimate
excuse for turning in assignments late. However, I will generally permit late work under
the following conditions for full credit:
- It isn’t a habit (after the second time, it will not be accepted).
- You talk to me about it.
- You made it up outside of class.
I will not expect you to make up quizzes or in-class work, but tests and homework are
always required.
Academic honesty: Cheating and plagiarism are forms of academic dishonesty. Cheating
means that you copied another student and there is evidence that you did so. Plagiarism
means that you copied, paraphrased, or summarized a source or classmate without
referencing them (this is a much lower threshold than copying: if it can be shown that you
have a similar work as someone else, then it is defined as plagiarism). At the least,
expect to fail the assignment (which may result in your failing the class). If this becomes
a habit, expect to be asked to complete assignments in the presence of a teacher and face
administrative disciplinary action.

First semester project:
Students will design and conduct an experiment to investigate the effects of response bias
in surveys. They may choose the topic for their surveys, but they must design their
experiment so that it can answer at least one of the following questions:
• Can the wording of a question create response bias?
• Do the characteristics of the interviewer create response bias?
• Does anonymity change the responses to sensitive questions?
• Does manipulating the answer choices change the response?
The project will be done in pairs. Students will turn in one project per pair.
A written report must be typed (single-spaced, 12-point font) and included graphs should
be done on the computer using JMP-Intro or Excel.
Proposal: The proposal should
• Describe the topic and state which type of bias is being investigated.
• Describe how to obtain subjects (minimum sample size is 50).
• Describe what questions will be and how they will be asked, including how to
incorporate direct control, blocking, and randomization.
Written Report: The written report should include a title in the form of a question and
the following sections (clearly labeled):
• Introduction: What form of response bias was investigated? Why was the topic
chosen for the survey?
• Methodology: Describe how the experiment was conducted and justify why the
design was effective. Note: This section should be very similar to the proposal.
• Results: Present the data in both tables and graphs in such a way that conclusions
can be easily made. Make sure to label the graphs/tables clearly and consistently.
• Conclusions: What conclusions can be drawn from the experiment? Be specific.
Were any problems encountered during the project? What could be done different
if the experiment were to be repeated? What was learned from this project?
• The original proposal.
Poster: The poster should completely summarize the project, yet be simple enough to be
understood by any reader. Students should include some pictures of the data collection in
progress.
Oral Presentation: Both members will participate equally. The poster should be used as
a visual aid. Students should be prepared for questions.
