<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0.7126 slope of child height on mid-parent height (inch per inch) (n = 934, 95% cluster-bootstrap interval [0.613, 0.814]). Interpretation: The claim is the specific fraction two-thirds for mid-parent to child, 'on the average of many cases'. Galton computed it from this same material (Table 11), so the test is a recount with modern regression rather than independent data; an independent cohort is a second test. Mid-parent is (father + 1.08 x mother)/2 as in the dataset's midparentHeight column.";
