Categorical variable:A categorical variable is a variable that can take on a fixed number of possible values. Applications of Variables As mentioned above, variables are used in various other fields apart from Maths. Some of the fields where variables are significantly used are as follows: ...
Categorical variables can be further categorized as either nominal, ordinal or dichotomous. Nominal variables are variables that have two or more categories, but which do not have an intrinsic order. For example, a real estate agent could classify their types of property into distinct categories ...

Purpose To find out whether the association between two categorical variables are statistically significant Null Hypothesis There is no association between two variables Prior to using the chi square test, there are certain requirements that must be met. The data must be in the form of frequen...
Nominal Variables This type of variable describes categorical values, where the variable value is exactly one distinct value of a finite set of possible, mutually exclusive, and usually exhaustive values. Therefore, these variables represent distinct groups or categories without any inherent ordering or...
