Increasing sample size is often the easiest way to boost the statistical power of a test.
2.
They introduced the concepts of " Type II " error, power of a test and confidence intervals.
3.
The statistical power of a test is the probability that it correctly rejects the null hypothesis when the null hypothesis is false.
4.
This is closely related to probably approximately correct ( PAC ) learning, where the learner is evaluated on its predictive power of a test set.
5.
Egon Pearson ( Karl's son ) and Jerzy Neyman introduced the concepts of " Type II " error, power of a test and confidence intervals.
6.
One easy way to increase the power of a test is to carry out a less conservative test by using a larger significance criterion, for example 0.10 instead of 0.05.
