WebP values help researchers avoid publication errors, specifically Type I Errors. While still widely used in scientific research, misuse of P values is at the heart of what is referred to as the "replicability crisis". They are reported as a decimal between 0 and 1, with some threshold (usually 0.05) deemed the significance critical value. WebThe third concern is the abuse of p-values. Because in practice much impor-tance is attached to small -values and statistical significance—the number of stars p in a table—there are strong incentives for researchers to obtain more favorable p-values.
