Tests of Marginal Homogeneity
This test compares the distribution of ratings given to items when the same items are assessed by two raters. This can be performed using nonparametric tests>legacy dialogue>2 related samples or nonparametric tests>legacy dialogue>related samples and choosing the marginal homogeneity option. The output produces a standardised test statistic and its p-value which can be quoted.
