Interpretation: Galton derived one-third by halving two-thirds and reported that direct observation gave about two-fifths, which he disregarded. The test is that direct observation on his own records. Single-parent slopes are expected to exceed half the mid-parent slope whenever spouses' heights are correlated.";
