Abstract

The long-standing problem of statis- tical vs. clinical significance is examined in the context of the apparent over-dependence on, and naive interpretation of, levels of statistical sig- nificance. Issues of statistical inference, partic- ularly the magnitude (vs. the significance) of an effect, are discussed and a few basic measures for estimating the magnitude of an effect or (clinical) treatment are noted as well as suggestions for further reading.
