PowerSpeed

How much power do you need? One of the most important issues when considering an experimental design for analysis is whether or not the design has adequate power to detect a change in the response that is of interest from a scientific or business point of view.

In many instances, the "power" or sensitivity of the experiment is the most critical aspect of the design in assuring sound, reliable results. If the power of an experiment is low, then it is likely that the experiment will be inconclusive. On the other hand, if the power is too high, resulting in a sample size that is too large, then valuable resources will be wasted on producing a result with limited practical importance.

This session addresses the importance of conducting a power analysis before performing a test or an experiment, to ensure the most appropriate design is used.
