The factorial survey is an experimental design consisting of varying situations (vignettes) that have to be judged by respondents. For more complex research questions, it quickly becomes impossible for an individual respondent to judge all vignettes. To overcome this problem, random designs are recommended most of the time, whereas quota designs…

Purpose: The purpose of this research is to examine the effects of scenario planning on participant ratings of resilience. Design/methodology/approach: The research design is a quasi experimental pretest/posttest with treatment and control groups. Random selection or assignment was not achieved. Findings: Results show a significant difference in…

Research methods and statistics are core courses in the undergraduate psychology major. To assess learning outcomes, it would be useful to have a measure that assesses research methods and statistical literacy beyond course grades. In two studies, we developed and provided initial validation results for a research methods and statistical knowledge…

Functional behavioral assessment (FBA) is an empirically supported intervention associated with decreasing problem behavior and increasing appropriate behavior. To date, few studies have examined multimedia approaches to FBA training. This paper provides the outcomes of a randomized controlled trial across three university sites and evaluates…

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs, as well as for providing feedback to teachers and administrators. In this study, the authors examined whether using anchoring vignettes in web-based surveys improved the validity of teachers' self-assessments…

This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from…
