2015 Webinar Profile

Considerations for Validity in Experimental and Quasi-Experimental Research
Presented by Joseph Keebler, Wichita State University
Monday, June 15, 2015

ABOUT THE WEBINAR

Keebler
Joseph Keebler
In this webinar, Joseph Keebler will discuss the importance of threats to validity and their implications for design in applied and quasi-experimental research. The webinar will emphasize construct, statistical conclusion, and internal and external validity. Keebler will review each type of validity with a focus on aspects of research design that can prevent researchers from making empirical judgments and causal inferences.

This webinar is appropriate for researchers with knowledge of experimental design but little or no familiarity with validity. It will be valuable for those in either academic or industry settings. Keebler will focus on design implications for research when it is hard or impossible to have a well-controlled experiment. He will detail some of the best ways to handle this lack of control by discussing various design approaches and methods for analyzing data to test for threats to validity. This will include designs that don't have control groups, designs lacking pretests, and time-series designs.

ABOUT THE PRESENTER
