Required Course Materials
David Moore, The Active Practice of Statistics. (APS)
Paul Velleman, ACTIV STATS CD-Rom
Bundled together in one package. Bring them both to class each day.
A diskette formatted for IBM compatible computers. Bring it to class each day.
A calculator for simple addition, subtraction, multiplication and division functions. You may use a calculator at all times, including when you take quizzes.
We will provide headphones for use in lab. You are expected to work on your own (as well as in lab) with the lessons and problems on your CD ROM. If you use a public lab to do this, you will need your own headphones since the CD ROM is instructional and has many videos and voice instructions. If you can work in a private location, such as your own home, you can probably get by without headphones.
About This Class
Because learning statistics is very much like learning a language, class attendance is required. If you fail to master step 1, step 2 becomes very difficult to master, and step 3 becomes impossible to master, so do not fall behind or skip classes.
This class is a non-technical introduction to statistics. With the aid of the computer, you will not have to spend much time doing calculations or memorizing formulas. We will emphasize conceptualizations and the practical analysis of real data from real problems. Most of the data sets presented are real, and many of the data sets presented in the problems in Moore=s textbook are also incorporated into the homework problems presented in ActivStats. Thus with a few clicks of a button (or a rodent), you can access and analyze large data sets which would otherwise take you a very long time to prepare for analysis.
We meet every Tuesday and Thursday at 11:15 in 440 Blegen Hall. Make sure you arrive on time and stay for the entire class. Let me know if that poses a problem for you. The class schedule is listed below. It is very important that you remain current in your work. If you do not read the material in the Moore book when it is assigned, or if you have failed to do your ActivStats lessons and homework, then you may have difficulty following what we do each week in class.
Most class time will be spent working on group and individual projects, studying ActivStats lessons using your CD rom and earphones, learning how to use DataDesk and solving problems using real data sets and the DataDesk analysis program.
After the class schedule, I have listed the homework assignments. There will be daily assignments in class using the individual computers in 440 Blegen, as well as two group research projects. The group research projects will be described in class. If you miss class, you may have some difficulties completing your homework assignments. Your grades will be based on your performance on the quizzes, assigned homework, in-class assignments, group projects, and class participation and discussion.

Homework Assignments
The assignments below should be handed in on the due date. Assignments handed in late will be docked a grade. You should work more of the problems than just those to be handed in for grading, particularly if you have difficulty with any of the topics. You should do the odd numbered problems and compare your answers with those listed in the back of the APS book. You should also do the extra problems in ActiveStats to make sure you understand the concepts. Some ActiveStats problems will also be assigned. Some of the quiz items will be selected from among the APS and ActivStats problems not assigned so a good way to study for the quizzes is to work extra problems.
April 6 Hand in APS 2.4 (2-3 in ActivStats), 3.7 (3-9 in ActivStats), 3.14 (3-12 in ActivStats).
April 8 Hand in APS 4.8, 4.11 (4-9 in ActivStats), 4.12 (4-10 in ActivStats), 6.2. (6-6 in ActiveStats), and problem 6-8 in ActivStats.
April 15 Hand in APS 5.4, 5.8, 5.12, 7.1 (7-5 in ActivStats), 7.3 (7-7 in ActivStats), and 7.8 (7-10 in ActivStats).
April 20 Hand in APS 8.2 (8-3 in ActivStats), 8.4 (8-5 in ActivStats), 8.8, 9.2 (9-5 in ActivStats), 9.12 (9-8 in ActivStats)
April 22 Hand in APS 10.2, 10.6, 10.14, 11.4, Review 2 problem on p. 140, Review 6 problem on p. 142.
May 4 Hand in APS 12.6, 12.9 (12-7 in ActivStats; use the Amanipulations@ menu, followed by Agenerate random numbers@, then fill in A1" for variable and then type in the number of cases, check ABernoulli@ and type in the probability of success, given in the problem itself.; then get the required stats), ActivStats 13-2 (not in APS), APS 13.8, ActivStats 13-11 (not in APS).
May 6 Hand in ActivStats 15-1 and 15-2 (neither one is in APS), APS 15.6-15.10, 16.4 (16-5 in ActivStats), 16.6, 16.8 (16-7 in ActivStats).

(When you do ActivStats 17-1, after you load Homework and DataDesk, click on HINT and it will show you how to obtain confidence intervals, after you click on CALCULATE---ESTIMATE. Follow all instructions carefully. When you do APS 18.8, enter the data into data desk as you have before. Click on the DataDesk icon directly, do not enter it through the Homework icon. Then use DATA---NEW---RELATION and DATA---NEW---BLANK VARIABLE to enter the data into a new variable icon which contains the healing rates for the 14 newts.)
May 20 Hand in APS 19.3-19.5, 19.10 (19-4 in ActivStats), ActivStats 19-3, 20.4 (20-3 in ActivStats), 20.6 (20-4 in ActivStats). 20.10 (20-6 in ActivStats). (To do ActivStats 19-3, click on CALCULATE---TEST and be sure to enter the correct values for sigma and for the null hypothesis before you click on SHOW RESULTS. For ActivStats 20-4, you need to do both a t-test under CALCULATE---TEST and a t-confidence interval under CALCULATE---ESTIMATE.)
May 27 Hand in APS 21.2 (21-6 in ActivStats), 21.6, 22.4, 22.10 (22-7 and 22-8 in ActivStats), 22.16, 23.2 (23-2 in ActivStats), 23.8 (23-5 in ActivStats).
