Key Concepts

Statistical Power

Statistical power is the probability that a hypothesis test will correctly reject a false null hypothesis. It reflects the test’s ability to detect an effect when one truly exists, thus minimizing the occurrence of a false negative result.

Type II Error

A Type II error occurs when a test fails to reject the null hypothesis even though the alternative hypothesis is true. The probability of making this error is denoted by ?, and 1 - ? therefore represents the likelihood of avoiding this error and correctly identifying a true effect.
