Deep Dive Workshop: "I've got the power"

How anyone can do a power analysis on any kind of study using simulation

Friday, 9:30 am to 12:30 pm
Limited seating (to apply: click here)

Recent discussions regarding replicability have stimulated increased emphasis on sufficiently powering studies to obtain effects that are robust to repeated investigation. However, appropriate methods for doing so have historically been under-explained, and many contemporary power analysis packages provide limited, black-box approaches that cannot accommodate commonly-used complex models. This workshop provides straightforward guidelines for designing flexible power simulations (using SPSS, SAS, MPlus, and R) that use researcher-specified parameters to maximize robust and replicable study results.

Who Should Attend

This workshop is geared toward individuals who have advanced methodological experience and are well versed in basic statistical procedures, including ANOVA, regression, and multilevel modeling. We will be using several statistical packages, and will not be covering the basics of how to utilize these programs. Although syntax will be provided for SPSS, experience with SAS, MPlus, and/or R is preferred in order to be able to follow along with examples. If there are several members of your lab who are interested in participating, we recommend sending the most senior member. We are happy to share all materials so participants can help teach others.

Workshop Presenters

  • Sean Lane is a Postdoctoral Fellow at the University of Missouri.  He develops statistical methodologies with a focus on dynamic systems to characterize emotion regulation and its effects on health and relationship outcomes.  He investigates how these processes are modulated by alcohol use and differ between healthy and clinical subgroups.
  • Erin Hennes is an Assistant Professor at Purdue University. She uses a multi-method approach that includes experimental, longitudinal, and content analytic methods. In particular, she examines cognitive and motivational biases in the processing of scientific and media information about contemporary social justice issues such as environmental sustainability and racial and gender inequality.
  • Tessa West is an Associate Professor at New York University.  She conducts research on the dynamics of social perception at the level of the dyad and group, and develops analytic methods for examining accuracy and bias in person perception.  She also examines methodological issues in the study of intergroup relations.
