Practical Study Design - Gordana Popovic

Good study design is crucial for answering your research questions. No amount of post processing or statistical expertise can compensate for poor or inadequate study design. I will review basic concepts like confounding, controls and randomization; show you how to estimate an appropriate sample size for your question; talk about how to conduct good observational studies; and describe how to use blocking in your study design, so that you can get more power with a smaller sample size.
