Ordinal-Variables

Ordinal variables are a type of categorical variable that possess a clear, ordered relationship among their categories. Unlike nominal variables, which have no inherent order, ordinal variables allow for ranking or ordering of the categories, such as “low,” “medium,” and “high.” This ordering is significant because it conveys information about the relative position of each category. In data analysis and machine learning, understanding ordinal variables is crucial, as they require specific techniques for encoding and modeling, such as ordinal encoding or ordinal logistic regression, to accurately capture the relationships within the data.

Variable is a quantity that may vary from object to object. For example, we measure heights of 50 mango trees in a selected plot and arrange the results in a table. Here, the quantity that vary…
