Simplify Your Sample Size and Study Design Calculations
Study Design Calculators provides a cloud-based set of tools that will allow you to perform calculations, generate designs and randomize subjects from any platform, including PCs, Macs, tablets and even phones.
All of our calculators and generators are throughly tested against academic publications, textbooks and existing software. At Study Design Calculators, we believe in transparency, which is why we make the code used for every result open source.
Study Design Calculators offers 38 calculators to determine sample size and power requirements for 132 hypotheses (and we are adding more all the time). All calculations are throughly tested against existing software packages and multiple references, including textbooks and journal articles.See our calculators or Try one out!
