Explanation:
Detailed explanation-1: -Note that age is always a number, so age can never be nominal or ordinal. Moreover, Age is always measured from zero, so there is always a “true zero” point. Thus, age cannot be an interval variable.
Detailed explanation-2: -Age is typically considered to be measured on a ratio scale. This is because age has a true zero point, which means that a value of zero represents the absence of age. In addition, it is possible to perform mathematical operations such as addition, subtraction, multiplication, and division on age values.
