With ordinal data, you can safely determine the mode and median, and you can use non-parametric statistical tests like the Mann-Whitney U test or the Wilcoxon signed-rank test.
Designing Effective Ordinal Questions for Surveys

Similarly, an age of 20 years is exactly half of 40 years, and a length of 0 meters means there is no length at all. These two data types sit at different levels of the measurement hierarchy, dictating the mathematical operations you can legitimately perform and the statistical tests you can apply.
Designing Effective Ordinal Questions for Surveys
Understanding the distinction between ordinal and ratio data is fundamental for anyone working with quantitative information, from researchers and analysts to students and business professionals. A common example is survey responses on a Likert scale, such as "Strongly Disagree," "Disagree," "Neutral," "Agree," and "Strongly Agree.
