A student with a master's degree is presumed to already have a bachelor's degree. Which type of data does this represent?

Ratio data possesses a true zero point and allows for comparison of absolute magnitudes. Examples include height and weight, where one can say that one value is twice another. In this case, educational degrees do not fit this definition because there is no true zero in education; the attainment of degrees is not measured by absolute quantity but by levels of achievement.

Nominal data categorize variables without any order or ranking. Examples include gender or types of fruits. In the context of educational degrees, nominal data would not apply since degrees can be ordered based on their level of achievement, making this choice incorrect.

Interval data consist of ordered categories with equal distances between values but no true zero point. Temperature in Celsius is a common example. Educational degrees do not fit this category either, as there is no uniform scale of intervals between the levels of education, and the degrees cannot be measured in consistent units of distance.
