Empirical Power Analysis Tool for fMRI

Functional magnetic resonance imaging (fMRI) research has transformed our understanding of human brain function and disease, but recent work has exposed an endemic lack of statistical power (i.e., ability to detect effects of interest) and a need for power analysis tools that meet the demands of the typical user. We propose to create a web-based power calculator tailored to typical fMRI studies that only requires the user to specify information readily available to them. By enabling researchers to more easily and accurately plan studies for desired levels of power, this power calculator will promote more robust and reproducible findings in the field.
