Class 4: Power Calculations

This module presents a first approach to power calculations required to define an adequate sample size for RCT studies. Selecting an appropriate sample size is important in order to make sure that the lack of significant results in an RCT study can be attributed to an ineffective treatment, and not to a deficiency in the sampling strategy. This course will introduce the main elements affecting sample-size calculation and how to correctly estimate sample size requirements.
