Dear Visitors,

Since retirement from Iowa State University I have had little reason to update this site.  I appreciate the interest of the over 170K visitors who have used it over its lifetime and hope you have found the materials here useful.  However, when the time comes in the fall of 2024 to renew payment for the hosting of the site, I intend to let it expire.  So, if you want copies of the materials posted here, please download them now.

I intend to continue the existence of Analytics Iowa LLC, but this site (and probably the analyticsiowa.com domain) will no longer be in use.

Thanks for your interest!

Steve Vardeman

I would like to announce the free open-source availability of a high-quality engineering statistics text in .pdf form.  The book Basic Engineering Data Collection and Analysis by Vardeman and Jobe, originally published by Duxbury/Thompson Learning/Cengage is now available for download under a (CC BY-NC-SA) 4.0 International license through the Iowa State University Digital Press.  It can be found at:

https://www.iastatedigitalpress.com/plugins/books/127/

and has been assigned the DOI

https://doi.org/10.31274/isudp.2023.127

This book is essentially a revision/second edition of Statistics for Engineering Problem Solving by Vardeman that won the American Society for Engineering Education 1994 Meriam/Wiley Distinguished Author award (given biennially for “an outstanding new engineering text”).

The book has answers for end-of-section exercises.  All datasets in the book are on the web page in digital form.  Chapter formula sheets are on the web page.  The text’s solutions manual for the end-of-chapter exercises is currently being processed for posting and will appear in due course.  And there are plans unde way to produce and post a supplement giving R code and output for the book’s examples.

Professor Jobe and I offer this book with the hope that it proves useful to many instructors and engineering students for years to come.
