"A Mann-Whitney U test was conducted to evaluate the difference in customer satisfaction ratings between the Control group and the Experimental group. The results indicated a significant difference, with the Experimental group (Mean Rank = 65.4) showing higher satisfaction than the Control group (Mean Rank = 40.2), $U = 1500.5$, $z = -3.45$, $p < .001$."

In the hierarchy of measurement levels (Nominal, Ordinal, Interval, Ratio), ordinal data sits in the middle. It possesses the characteristics of nominal data (distinct categories) but adds a rank order.

Ordinal data—data with categories that have a logical order but unknown or unequal intervals between values—is ubiquitous in social science research, particularly in survey methodologies (e.g., Likert scales). Despite its prevalence, the statistical analysis of ordinal data remains a subject of confusion. Many researchers erroneously apply parametric tests (like t-tests or ANOVA) designed for interval/ratio data. This article explores the theoretical necessity of nonparametric statistical methods for ordinal data and provides a step-by-step tutorial for executing these analyses in IBM SPSS Statistics.
