WebMay 24, 2024 · A major advantage of using confidence intervals as compatibility intervals is that it directs our attention to the concrete hypotheses (effect size values) included in the interval, rather than encouraging blurry statements like ‘uncertainty is high’ or ‘low’ ( Greenland, 2024b ).
