Empirical assessment of published effect sizes and power in the recent cognitive neuroscience and psychology literature

Fig 5

Lower estimates of FRP for various H₀:H₁ odds and bias values.

(A) FRP for a wide range (0.1–1,000) of H₀:H₁ odds on a 10-based logarithmic scale (horizontal axis). (B) FRP for the 1–30 range. The dotted vertical lines denote the same H₀:H₁ odds in both panels for easier comparison (H₀:H₁ odds of 1, 2, 3, 4, 5, 10, 15, 20, 25, and 30). Note that the vertical axis begins at 0.1 in Panel B for better visibility. FRP is provided for a range of bias values. For example, bias = 0.1 means that 10% of results that would be reported as statistically nonsignificant in the absence of bias will be now reported as statistically significant. See further elaboration on bias in the text.
