Ask any Statistics/Probability/Math Question

Some Definitions

1. Power Analysis

To determine the power of your study it is uncommon to take an inappropriate "one-size-fits-all" approach.

In Simple power analysis (SPA) we interpret graphs of electrical activity over time. More advanced form is the Differential power analysis (DPA) which computes intermediate values with the help of statistical analysis.

2. Sample Size

The validity of the study is determined with the help of sample size. So it is of prime importance to know the sample size.

3. Power

Power is the complement of type II error, which means it is Pr( Reject the null hypothesis when it is false) i.e, a correct decision. The more the power the more better is the test.
