Detailed explanation-1: -Anything that can vary can be considered a variable. For instance, age can be considered a variable because age can take different values for different people or for the same person at different times. Similarly, country can be considered a variable because a person’s country can be assigned a value.

Detailed explanation-2: -A variable is a characteristic that can be measured and that can assume different values.

Detailed explanation-3: -Categorical variables They are sometimes recorded as numbers, but the numbers represent categories rather than actual amounts of things. There are three types of categorical variables: binary, nominal, and ordinal variables.

Detailed explanation-4: -A categorical variable that can take on exactly two values is termed a binary variable or a dichotomous variable; an important special case is the Bernoulli variable.

Detailed explanation-5: -What are dependent variables? A dependent variable is a variable in an expression that depends on the value of another variable. For example, if y = 2x, then y depends on x. So, if x = 1, then y = 2.
