What’s ordinal knowledge?
Ordinal knowledge is quantitative knowledge during which variables are organized in ordered classes, akin to a rating from 1 to 10. Nonetheless, the variables lack a transparent interval between them, and values in ordinal knowledge don’t at all times have a good distribution.
Therefore, the extent of buyer satisfaction is an instance of ordinal knowledge. Its variables might be:
- Very Happy
- Happy
- Impartial
- Dissatisfied
- Very dissatisfied
Utilizing ordinal knowledge, you possibly can calculate the frequency, distribution, mode, median, and vary of variables.
Having outlined ordinal knowledge, you might surprise about different knowledge sorts, akin to nominal, interval, or ratio knowledge. How do they differ from ordinal knowledge? Listed below are some fast definitions:
- Nominal knowledge is a classification of information whose variables have a finite set of values and classes that are not ordered. With nominal knowledge, you measure variables akin to sort of employment, which has a number of outcomes, akin to freelance, full-time, or hybrid work.
- Interval knowledge is a kind of information the place the interval between two values is not fixed. Interval knowledge come up in some ways, for instance, when measuring time intervals or when the distinction between two measurements varies. The most typical method to characterize interval knowledge is utilizing a desk with columns for every vary’s higher and decrease bounds.
- Ratio knowledge is a kind of information used for statistical evaluation. The ratio knowledge doesn’t present any details about the values it represents. This data should be obtained from different sources referenced by the ratio knowledge. It’s typically used within the evaluation of monetary data however will also be utilized to different varieties of knowledge.
5 examples of ordinal knowledge

- The Kruskal-Wallis take a look at
- The Mann-Whitney U take a look at
- Wilcoxon rank-sum take a look at
- Temper’s Median take a look at
Ordinal knowledge is a knowledge sort that ranks values from least to best. In different phrases, ordinal knowledge is ranked or ordered.
Kruskal–Wallis H take a look at
The Kruskal-Wallis take a look at is a non-parametric take a look at used to match the medians of three or extra unbiased teams. It’s used when the info shouldn’t be usually distributed, and the variance between teams is unequal. The Kruskal-Wallis take a look at may also examine two dependent teams – earlier than and after photos of a web site redesign.
Mann-Whitney U take a look at
The Mann-Whitney take a look at is a non-parametric take a look at used to match the median of two unbiased samples. It may be used when there’s ordinal knowledge, akin to scores on a scale from 1 to five, or when there aren’t any clear teams within the knowledge.
Wilcoxon signed-rank take a look at
The Wilcoxon signed-rank take a look at is a non-parametric take a look at that can be utilized for knowledge units with or with out regular distribution. It is a substitute for the t-test in instances the place the info would not have a standard distribution.
When operating a t-test, the idea is that the underlying distribution of the info is regular, however this assumption will be unsuitable.
For instance, when testing the distinction in peak between two teams, for example one group has a mean peak of 180 cm and the opposite group has 170 cm. You will not see any vital distinction of their heights.

Inferential statistics, then again, predict what could occur sooner or later primarily based on the info you could have. You should use ordinal knowledge to gather insights, create hypotheses, and even draw conclusions with the 4 exams described above.
The Kruskal-Wallis, Mann Whitney U, and Wilcoxon signed-rank sum exams all analyze ordinal knowledge. They’re all nonparametric exams, which means they do not depend on any assumptions about knowledge distribution.
Descriptive analytics – ordinal knowledge
Descriptive analytics collects, analyzes, and stories knowledge about occasions which have already occurred. This differs from predictive analytics, which predicts future occasions primarily based on historic knowledge. Descriptive analytics helps companies determine patterns prior to now to enhance their future decision-making.
In descriptive analytics, the purpose is to seek out patterns in current knowledge, not predict what’s going to occur sooner or later. Descriptive analytics goals to seek out cause-and-effect relationships between previous occasions and use these relationships to foretell future occasions.
In contrast to different evaluation strategies, descriptive analytics can be utilized anytime with any knowledge obtainable. This makes it extra accessible for smaller companies with inadequate sources for predictive fashions or massive datasets required by different strategies.
