StudySize Studio, a guided calculator for research design
An interactive toolkit helps medical researchers choose sample-size calculators for different study designs.
Field notes
The homepage uses a decision tree rather than asking visitors to pick from an unexplained calculator list. Its visible branches cover estimation, group comparison, association, diagnostic accuracy, and prediction/modeling, with examples such as prevalence, hazard ratio, sensitivity, and regression. The surrounding tool list extends into randomisation, blinding, figure generation, protocol building, scenario comparison, and decision support. The page labels the product version 1.45 and invites bug reports and beta feedback.
