Fisher exact test, comparison among Groups 1–3, P = 0.007 (P < 0.0167 Holm’s sequential Bonferroni correction). Holm’s sequential Bonferroni correction procedure: Since the overall difference among the three groups is significant in handedness (Fisher exact test, P = 0.0079), now comparing the smallest P value first, which is between Groups 1 and 3 P = 0.007 < 0.05/3, 0.0167, so it’s significant; now compare the second smallest one between Groups 2 and 3, P = 0.02 < 0.05/2, 0.025, still significant; but the third significant P value between Groups 1 and 2, 0.6 is not significant.
