Reading a Heritability Estimate Together With Its Confidence Interval
Trains the habit of never quoting a point estimate bare. The seed paper's headline 17% for reading pitch carries a 95% CI of 9 to 24%; F1 of [a] is 9% with CI 2 to 15%, and F4 of [i] is 9% with CI 1 to 17% — an interval wide enough that the two 9% figures are barely distinguishable from near-zero. Also the place to state that 41 of the 72 measures came in under 5%.
Questions this Concept answers
- Why is a point estimate of \( 9\% \) carrying an interval of \( 2\% \) to \( 15\% \) weak evidence for a substantial genetic contribution?
