Inferential statistics are descriptive

Abstract

NHST is a useful tool for communication among researchers at the frontiers of scientific knowledge. I contend that inferential statistics are used primarily as descriptive landmarks in negotiating uncertain terrain, and that fashioning suitable null hypotheses can be nontrivial. Momentum effects in tennis are served as an example. Research advances both by both magnifying and isolating effects, and p values are valuable benchmarks in this endeavour. An increased focus on the locus of effects at the level of the individual is desirable. These recommendations are orthogonal to the abstract logic underlying NHST and do not diminish its utility.
