CAUSAL GENERALIZATIONS
PROJECTS

Tipton (PI) & Hedges (co-PI)
The Generalizer is a free webtool that guides K-12 researchers through the process of (1) designing a sample recruitment plan with generalization in mind and (2) reporting where the results of a study may (or may not) generalize well.
Funded by the Spencer Foundation (2014-2018)

Tipton (PI)
& Spybrook (co-PI)
In this project, we will design a new webtool that for designing cluster randomized trials in K-12 education with both statistical power and generalizability in mind.
Funded by the Institute of Education Sciences (2017-2022)

NATIONAL STUDY OF LEARNING MINDSETS
Yeager (PI)
In this study, a randomized trial of 9th graders was conducted within a stratified random sample of 76 high schools in the United States.
I was involved in the design of the study, as well as in subsequent analyses related to the generalizability of findings.
