GHOST: An Officially Recommended Practice

Part of the SpringerBriefs in Statistics book series (BRIEFSSTATIST)


This chapter gives a brief account of the misuses and abuses of Null Hypothesis Significance Testing (NHST). It also examines the most often recommended “good statistical practice,” called here Guidelined Hypotheses Official Significance Testing (GHOST). GHOST is a hybrid practice that appears as an amalgam of Fisherian and Neyman–Pearsonian views. It does not ban the use of significance testing, but the choice of the sample size should be justified, and estimates of the size of effects and confidence intervals should also be reported.
