- Summary:
-
This paper presents a visual analogy that may be used by instructors to teach the concept of statistical power in statistical courses. Statistical power is mathematically defined as the probability of rejecting a null hypothesis when that null is false, or, equivalently, the probability of detecting a relationship when it exists. The analogy involved a group of hikers in desert heat who are faced with the possibility that a pool of water seen by only one hiker is a mirage. Effect size, sample size, and significance level are discussed in terms of the mirage analogy. Type I errors, error variance, and directionality are also discussed in terms of the optical analogy.
