Truman AP Statistics

New to Truman this year, AP Statistics will prove to be very valuable in your college career.

The teaching of statistics has changed tremendously over the last 10 years or so. With the introduction of computers and powerful graphing calculators into the classroom, the student will have a chance to study the behavior of the data rather than spending time trying to solve the problem. As you progress through the year, you will find that you are communicating your ideas about 50% of the time and solving the other 50% of the time.

Our classroom will be utilizing all of this technology through laptops and TI-83+ calculators. With Smart boards inside the classroom students will be able to follow along at their table. The programs we will be relying on the most is Fathom and JMP IN. Fathom is a great tool that allows students to get a "feel" for the data. It is visually breathtaking and creates an interactive environment. JMP IN is the workhorse of the course. This software can handle vast quantities of data for analysis. We will be performing several activities utilizing both programs with emphasis on easing you in and progressively making activities more challenging throughout the year.

As with all AP courses, you will have an opportunity to take the AP Statistics exam sometime in May. If you elect to write the exam and do well, this can be used towards a college credit. Our goal is for everyone to take and pass the exam.

Course materials are as follows:

  • Textbook: Watkins, A.E., Scheaffer, R.L. & Cobb, G.W., (2004), Statistics In Action; Understanding a World of Data, Key Curriculum Press, Emeryville, CA.

  • Workbook: Rossman, A.J., Chance, B.L., Van Oehsen, J.B., (2002), Workshop Statistics ; Discovery with Data and Fathom (2nd Ed.), Key Curriculum Press, Emeryville, CA.

Students can use the internet for several resources. You may click here to access the publishers website which contains information and help specific to our textbook. I also encourage you to look at the following links at the beginning of every chapter:

We will also be doing several surveys during the year. I have set up an account for our class at Keypress to take these surveys online. I will provide you the username and password required to access the web site in class. Click here to link to the site or the button to the left labeled Fathom Surveys.


There are two semesters per year: September - January and February - June. Each semester is divided into three marking periods (terms).

For each term your grades are determined by the following: Class work = 25%, Homework = 25% and Tests = 50%.

At Truman, a passing grade is 65% and the grades are cumulative over the three terms per semester. For example, if you get a 70% in term 1, a 75% in term 2 and a 65% in term 3, your cumulative final grade would be 70% x 33% + 75% x 33% + 65% x 33% = 70%

However, there are ways to earn extra credit throughout the semester.

  Presentations Getting involved in class discussions and presenting homework at the board
  Question of the Week (QOW)

Every week on this web site, a new question will be posted covering concepts taught in class. Answer the question and receive 5 points towards your grade.

An archive of the questions and there solutions are posted here.

  Discovering the Picture In the upper right hand corner of this page is a small picture. The first student who correctly guesses what it is will earn 10 points towards their grade. The picture will correspond to the unit we are working on in class and will change once a term.

You can submit your answers to both the QOW and the Picture to apstatistics@svleck.com. Be sure to indicate what you are submitting in the subject line.

Question of the Week

Only an answer explaining how you found the solution will be accepted.

Researchers at Stanford studied whether reducing children's television viewing might help to prevent obesity. Third and fourth grade students at two public elementary schools in San Jose were the subjects. One of the schools incorporated a curriculum designed to reduce watching television and playing video games, while the other school
made no changes to its curriculum. At the beginning and end of the studey a variety of variables were measured on each child. These included body mass index, triceps skinfold thickness, waist circumference, waist-to-hip ratio, weekly time spent wathcing television, and weekly time spent playing video games.

a. Identify the observational unit
b. Identify three quantitative variables
c. Identify one categorical variable
