Effect size - one size doesn't fit all

There remains a pendulum swing to avoid p-values, but the binary, use or don't use p-values may be replacing one problem with another. This paper elaborates on the use of p-values and effect sizes, points out their utility and reminds that the context of the question remains critically important. There is no single measure that provides the sole value of a study. The over or under interpretation of various measures is cautioned. Researchers need to keep in mind there is bio in biostatistics and statistics in biology and medicine. Both are needed to understand results in context.
