a) HypothesesHo:M1=M2=M3 (The median test scores are equal)Ha:At least two of the samples differb) Significance level=0.05c) Critical value and rejection region
Reject the null hypothesis if H>5.99d) Test statistic
e) DecisionSince 6.06 5.99 (0.025 < p-value < 0.05), we reject the null hypothesis
f) Pairwise comparisons
The result of pairwise comparisons using the equation above show in the table below
