Which of the following variables has a fixed or true zero point? Years of school completed OccupationGenderMarital status

To determine which of the variables has a fixed or true zero point, we need to understand what a true zero point means. A true zero point indicates the absence of the quantity being measured.

1. Years of School Completed: This variable can have zero, which indicates no years of schooling. Therefore, it does have a true zero point.

2. Occupation: This variable does not have a true zero point. Different occupations cannot be quantified in a way that indicates a complete absence (zero) of occupation.

3. Gender: This is a categorical variable and does not have a zero point as it represents categories without quantitative measurement.

4. Marital Status: Similar to occupation and gender, this is also a categorical variable with no inherent zero point.

Conclusion

The variable that has a fixed or true zero point is Years of School Completed.
