It is all too common today to see researchers make their “significance” claims or statements based on merely “p < .05,” a single piece of information from their statistical significance tests. This symposium calls for exposing the p value abuse in our research practices. After a brief historical review of statistical significance testing and its positive role in helping scientific decisions, its limitations and widely spread p value abuse phenomenon will be described in detail. More appropriate ways of using information generated from statistical significance tests will be introduced. Finally, related software will be introduced and illustrated.
