Time to Abolish “Statistical Significance”?
13th September 2019
Given the omnipresence of “statistical significance” in pedagogy and the research literature, it was interesting last year when the American Statistical Association made an official statement “ASA Statement on Statistical Significance and P-Values” (discussed here) which includes comments like: “Scientific conclusions and business or policy decisions should not be based only on whether a p-value passes a specific threshold. … A p-value, or statistical significance, does not measure the size of an effect or the importance of a result. … By itself, a p-value does not provide a good measure of evidence regarding a model or hypothesis.”
Jay, I’d like to hear your thoughts on this.
