Analysis 1: Cross-tabulation of Blood Type and Personality

In Survey 1’s ANOVA result (Table 1), 6 of the 8 items demonstrated the same results as those shown for blood type characteristics in the preceding psychology papers (Sato, 1992; Watanabe, 1994). Of these, 5 items were statistically significant at p < 0.05, or 4 items after the Bonferroni’s correction. The magnitude of the difference: partial η2 = 0.030 at the maximum, thus all the effect sizes were small.
