aThe Kruskal-Wallis statistic, a test of rank for nonparametric samples, was also conducted for each self-rated health to examine differences in the 3 groups. Results for the KW indicated significant differences in self-rated health between groups (KW = 23.194, df = 2, and 𝑃<0.0001), with those who are 65 to 74 having the highest health (rank sum = 1,510,000), followed by those who are 75 to 84 (rank sum = 943,626), and those who are 85 and older having the lowest health (rank sum = 277,376).
