When the p-value falls below the … WebMar 11, 2024 · The p value reflects the degree of data compatibility with the null hypothesis. Some recommend abandoning p value, others lowering the significance threshold to 0.005. A 0.005 threshold could increase sample sizes and costs as well as depress spontaneous research. Authors should provide actual p values, not just “ p < 0.05” or “ p ≥ 0.05”.
