Workshop 9 (half day)

It’s All About the Fundamentals! Staying Statistically Savvy in a Point-and-Click World

Presenter:      Rodney A. McCloy, Human Resources Research Organization (HumRRO)
Coordinator:   S. Morton McPhail, Valtera Corporation

For many practitioners, the exigencies of applied and field research require working with nonoptimal datasets. Such datasets impose difficulties for statistical analyses that many practitioners may never have considered or have paid little attention to since leaving graduate school. In addition, the advent of widely available and easily used statistical software may lead applied researchers to use complex analytical techniques that are inappropriate for the situation and configuration of the data. Finally, some practitioners may return to statistical analyses after some time away from them, having forgotten (or repressed) their earlier acquired knowledge. These conditions can lead researchers to erroneous conclusions or to an inability to review and evaluate the research of others.

This workshop is designed to help participants:

  • Identify which statistical techniques are appropriate in common applied situations and why they are appropriate
  • Identify critical assumptions underlying the techniques and the implications of violating them in field settings
  • Recognize and avoid common errors that practitioners make

Rodney A. McCloy has conducted and directed personnel research for nearly 20 years. He is well versed in many multivariate analytical techniques (e.g., covariance structure analysis, structural equation modeling, event history analysis, hierarchical linear modeling), and he has applied these techniques to numerous research questions, especially those involving personnel selection and classification, job performance measurement and modeling, and attrition/turnover. His recent research efforts include development of an unproctored, online, computer-adaptive figural reasoning test for use in a multiple-hurdle selection battery; technical support for development of an online career exploration tool; and development of methods for estimating interrater reliability in ill-structured research designs. He received his doctorate in I-O psychology, with specialization in psychometrics and statistics, from the University of Minnesota.
