Bill Kanasky, Jr., Ph.D. describes the scientific concepts of validity and reliability in research and why they are individually and collectively so important when conducting jury research. The question that validity helps answer is: are you measuring what you think you are measuring? Bill gives examples of how you can limit or improve your validity through witnesses and presentations in jury research. It's critically important to secure a clean read in your research and Bill explains how to achieve that.
Reliability in research refers to the consistency and repeatability of a measurement, so that if the same process is repeated under the same conditions, it should yield similar results. Having reliability in your data means you can count on the results and increases confidence in the findings to better guide decision-making on your case.
