STATDISK is a software program designed specifically for use with textbooks in the Triola Statistics Series:

*Elementary Statistics, 10th Edition**Elementary Statistics, Updated 9th Edition**Elementary Statistics Using Excel®*, Second Edition*Essentials of Statistics,*Second Edition*Elementary Statistics Using the Graphing Calculator: For the TI-83/84 Plus**Biostatistics for the Biological and Health Sciences*

STATDISK is referenced throughout the textbooks, and can be used for nearly all of the statistical procedures in the books.

For the first five books in the list above, all of the data sets from Appendix B are included in STATDISK, except for Data Set 4. The included data sets will be automatically available when the program is loaded.

For the Biostatistics book, all of the datasets in Appendix B are included and will be available when the program is loaded.

**A Quick Tour of STATDISK**
After saving STATDISK to your hard drive, unzip it or unstuff it to
extract the application file. Here are instructions from Mario Triola for
a quick walk-through to begin using STATDISK:

1. Run STATDISK and select **
DATASETS** on the main menu bar,
then proceed to select the data set named **
Bears**. Note that the bear weights are
in column 9.

2. Click on **
Data**, select **
Explore Data**, select column 9,
then click on **
Evaluate**. I believe that you will be impressed with what you see.

3. Ready to throw away your printed tables?
Click on **Analysis**, select **
Probability Distributions**, then
select any of the listed distributions and see how easy it is to get values or
areas. For example, try finding the *t
*value corresponding to 73 degrees of freedom and with an area of 0.025 to
its right. **No more problems with limitations
of printed tables!!!**

4. Now try a hypothesis test. Click on **
Analysis**, select **
Hypothesis Testing**,
then select the type of test. For example, select **
Proportion One Sample **and proceed
to use a 0.05 significance level to test the claim that *
p *= 0.25 given a sample size of *
n *= 200 with 70 successes. Click **
Evaluate **and **
Plot **to see results.
