A bar chart of median anxiety level by age group. We conducted the Kruskalr-Wallis H test to determine if there is a statistically significant difference between anxiety levels in different age groups. This test was selected due to the marked left shift in the data. Sample sizes in each group are reported in table 2. This test demonstrated statistically significant differences between groups (χ2 153.895 with 7 df, probability=0.0001).
