Ordinal data is a type of categorical data where the categories have a meaningful order or ranking, such as rating scales (e.g., "poor," "fair," "good," "excellent"). In contrast, categorical data, also known as nominal data, consists of distinct categories that do not have a specific order, such as colors (e.g., "red," "blue," "green"). While both types of data classify items into groups, ordinal data conveys a sense of hierarchy, whereas categorical data does not.

Are eye colors ordinal data?
no, they are categorical
What does categorical data vary mean?
Categorical data varies when there are a variety of different categories.
Why is ANOVA used for interval and ratio level data only and not used for nominal or ordinal level data?
ANOVA (Analysis of Variance) is used for interval and ratio level data because it relies on the assumption that the data is continuous and normally distributed, allowing for meaningful calculations of means and variances. Nominal and ordinal data do not meet these criteria; nominal data consists of categorical variables without a numerical relationship, while ordinal data has a ranked order but does not provide equal intervals between ranks. Consequently, ANOVA is not appropriate for these data types as it cannot accurately assess differences in means or variances.
What is categorical data?
Categorical data is the statistical data type consisting of categorical variables or of data that has been converted into that form, for example as grouped data.
What do categorical variables measure?
Categorical variables measure characteristics or qualities that can be divided into distinct categories or groups. These variables represent non-numeric data, such as gender, color, or type of vehicle, where each category is mutually exclusive. They help in organizing data into meaningful classifications, allowing for analysis of patterns and relationships within the data. Categorical variables can be further classified into nominal and ordinal types, depending on whether the categories have a natural order or ranking.
Are eye colors ordinal data?
no, they are categorical
Is Gender nominal or ordinal?
Gender is nominal. Nominal is categorical only; no ordering scheme. Ordinal level of measurement places some order on the data, but the differences between the data can't be determined or are meaningless.

True or false Data at the ordinal level are quantitative only?
False. Data at the ordinal level can be either quantitative or qualitative. In ordinal data, the categories have a meaningful order or rank, but the difference between the categories is not necessarily equal.
Can you do an ANOVA with nominal data?
The independent variable in ANOVA must be categorical (either nominal or ordinal). The dependent variable must be scale (either interval or ratio). However, it is possible to recode scale variables to categorical and vice versa in order to perform ANOVA. While this is a common practice in many social sciences, it is controversial. I have also seen studies where ordinal data is treated as scale in ANOVA. Personally, I do not endorse either practice as they are tailoring the data to fit the test instead of the proper method of selecting a test that fits the data.

What graphs are used for categorical data?
The graph that is most used for categorical data is the pie chart. Bar graphs have also been used for categorical data.

IS GPA nominal data or ordinal?
It is ordinal.
What is ordinal statistics?
Ordinal statistics or data is classified as ordinal if the values can be rated on a scale or put i order. Ordinal data can be counted but never measured.
