Study Design Calculators

My name is Christopher Louden. I created this website with one goal in mind: to simplify the study design process. Whenever I designed studies for clients, I found that I had to reinvent the wheel a lot. With this website, I have brought together the most commonly used techniques for study design, power and sample size calculation and randomization list generation.

My Mission

My mission is to bring to you a set of tools that will streamline your study design process. If there is anything that you need but do not see here, please let me know.
