| Power Analysis: A Simple and Effective Approach - Continuing Education - CTW | ||

| This workshop offers an introduction to power analysis and shows how to use it simply and effectively to plan studies and write grant applications. Power analysis is the art of finding and justifying a sample size for a planned study. Power is determined by such factors as the magnitude of the treatment effect, the sample size, alpha, and (for survival studies) the study duration. The goal of the power analysis is to balance these as a series of "what ifs," done most effectively with graphs that allow the researcher to grasp (and communicate) a range of options in a single picture, and then find the one that strikes the optimal balance of feasible sample size, reasonable assumptions, and acceptable power. We will show how to do this using Power And Precision. We will use examples from means, proportions, and survival analysis. This workshop is recommended for people new to power analysis, frustrated by power analysis, and who need to perform power analysis for survival studies. | ||
