In the numerical and statistical examination, data is characterized as a gathered group of data. Data, for this situation, could be whatever might be utilized to demonstrate or refute a logical estimate during an analysis.
Data gathered might be age, name, an individual's assessment, kind of pet, hair tone, and so on. In spite of the fact that there is no limitation to the structure this data may take, it is arranged into two primary categories relying upon its inclination—to be specific; categorical and mathematical data.
Categorical data, as the name infers, are normally grouped into a category or numerous categories. Mathematical data or numerical data refer to number variables.
Categorical data is an assortment of data that is partitioned into groups. I.e, if an association or office is attempting to get a biodata of its representatives, the subsequent data is alluded to as categorical. This data is called categorical on the grounds that it could be grouped by the factors present in the biodata, for example, education, position, and so forth.
Categorical data can include numerical values, for example, 1 acting as YES and 2 acting as NO, however, these numbers would be taken as characters rather than integers.
There are two types of categorical data, in particular; the nominal and ordinal data.
Nominal Data:
This is a kind of data used to name factors without offering any mathematical benefit. Begat from the Latin terminology "Nomen" (meaning name), this data type is called a subcategory of categorical data.
Ordinal Data:
This is a data type that relates to the order of the data. This means what order would be followed to categories of the data. It does not have any fixed/standard scale for ordering.
