A one-way ANOVA was conducted to explore the impact of age on levels of optimism. The optimism scale was from 1 to 30 and the number of total participants was 435. Subjects were divided into three groups according to age (Group 1 = 29 or below (n=147); Group 2 = 30 to 44(n=153); Group 3 = 45+(n=135)). There was a statistically significant difference at the p<.05 level for the three age groups (F= 4.6, p=.01). Despite reaching statistical significance, the actual difference in mean scores between the groups was quite small. The effect size, calculated using eta squared, was .02. Post-hoc comparisons using Tukey test indicated that the man score for Group 1 (M=21.36, SD=4.55) was significantly different from Group 3 (M=22.96, SD=4.49). Group 2 (M=22.10, SD=4.15) did not differ significantly from either Group 1 or Group 3.
