Test Validity Analysis – a free download


As you may already know, we have been busy working on a series of certification programs.

The first one, which started in April – and we’ll be running it again, starting in June – is the Foundations of Online Testing course.

During the first course we found that the topic people wanted help with most was determining the validity of test results.

Right now we are working Dr. David Reiley, Professor of Economics for the University of Arizona, to develop a theorem for calculating validity with a small sample size that is based on making a prediction prior to running a test.

We believe this will allow marketers to move more quickly as they test, and to make sound decisions with less information.

In the interim, we have put together a PDF file which takes you through the steps to quickly calculate test validity.

Feel free to download your own copy of Determining if a Data Sample is Statistically Valid.
