This appendix reviews some of the basic math skills that are necessary for the statistical
calculations presented in this book. Many students already will know some or all of
this material. Others will need to do extensive work and review. To help you assess your
own skills, we include a skills assessment exam here. You should allow approximately
30 minutes to complete the test. When you finish, grade your test using the answer key on
pages 644–645.
Notice that the test is divided into five sections. If you miss more than three questions
in any section of the test, you probably need help in that area. Turn to the section of this
appendix that corresponds to your problem area. In each section, you will find a general
review, examples, and additional practice problems. After reviewing the appropriate
section and doing the practice problems, turn to the end of the appendix. You will find
another version of the skills assessment exam. If you still miss more than three questions
in any section of the exam, continue studying. Get assistance from an instructor or a tutor
if necessary. At the end of this appendix is a list of recommended books for individuals
who need a more extensive review than can be provided here. We stress that mastering this
material now will make the rest of the course much easier.
