As there is too little data for ANOVA or Chi-Square test and, data are not normally distributed. it is decided to use the Kruskal-Wallis test. The calculations for the ranks for all the age groups combined are provided below: For the young (Y) group: Ty = 52.5 ; ny = 6 For the medium (M) group: Tm - 68 ; nm - 6 For the old (O) group: To-49.5; no - 6 What is the value of the statistic H? O0.49 O1.39 O1.61 O 3.93 O1.56
