You should not print out the textbook. It will not disappear. You can download the PDF for viewing on your own machine if this is handy for you. You will probably read some sections more carefully than others. Sections are referenced in the tentative scheule as needed.

Statistics textbooks vary in details; you will note differences if you look through other texts and references. We will use the conventions in this textbook. One weakness of this textbook is that the tables are difficult to use and, notably, difficult to print out in readable form. Here are some common tables in better form:

Standard Normal, Binomial, and T Tables

Calculators, Computers, PEDs (Personal Electronic Devices)

You may have a calculator already, but make sure that it is a scientific calculator which has the needed statistical functions. The TI graphing 83+, 84, 85, and 86 models are capable.

If you need to buy a calculator, I recommend the calculator TI-30XS Multiview. This does what you need for under $20. Fancier calculators may be more difficult to use. The bookstore sells the TI-30XS Multiview for under $20 .

Keep your calculator handy! You must have it for homework, exams, and in-class work.

However, here are some online calculators you may find helpful:

Basic Statistics and Standard Normal Distribution Calculators

Exams and Grading

Show your work on homeworks and exams! That is what I'm looking for, not just lists of answers--though of course correct answers are important. 

4 tests     4x100 = 400
1 final             200
20 homework 5x20  = 100
-----------------------
                    700 total

90-100%   A
80-90%    B
70-80%    C
60-70%    D
0-60%     F

The Course

This course addresses FDLTCC liberal education requirements (Competencies Across the Curriculum) in problem solving and technology. You should attend class everyday! This is the easy way to do well in any course, and it is especially true for math classes. There are exercises in the text for you to do, and these are usually answered at the end of each chapter. You will also get homework assignments on handouts, and you should complete then hand these in at the beginning of the next class. You homework grade is based on completing and turning in these homework handouts. You will also get sample exams which will be similar in length and content to the in-class exams. Let me know if there is are accommodations you need for the class.

A feature of statistics study is that one does not have to make up applications out of the blue. Applications abound! To be sure, our examples for studying statistics are somewhat contrived, for practical convenience. We do not need to handle 1,200,000 numbers when just 12 numbers will do. Theory, methods, and key steps are essentially identical for large and small sets. It just takes more labor handling large data sets.
