Question
Which of the following variables has a fixed or true zero point? Years of school completed OccupationGenderMarital status
Solution
The variable that has a fixed or true zero point among the options provided is "Years of school completed". This is because it is a ratio variable, which has a clear definition of zero. If someone has completed 0 years of school, it means they have not attended school at all.
The other variables - Occupation, Gender, Marital status - are nominal or ordinal variables. They do not have a true zero point. For example, there is no "zero point" for gender or occupation that indicates the absence of that attribute.
