Which dimension type includes fields such as quantity, sales, and profit?

The chosen answer, which is ratio dimension, is correct because ratio dimensions are characterized by the presence of an absolute zero point and are used to measure quantitative attributes. Fields such as quantity, sales, and profit are all quantitative metrics that can be expressed numerically and possess meaningful zero values, allowing for a wide range of mathematical operations, including addition, subtraction, multiplication, and division.

For instance, a quantity of 0 means that there are no items, which is a definitive starting point. Similarly, a profit of 0 indicates that there is neither gain nor loss, underscoring the practical use of ratio dimensions in business contexts.

In contrast, nominal dimensions are used for categorical data without inherent order, such as names or labels. Ordinal dimensions do provide a rank order, but they do not quantify the differences between values (for instance, rating scales). Interval dimensions allow for the difference between values to be meaningful but do not have an absolute zero (e.g., temperature in Celsius). Therefore, in the context of measuring concrete, quantifiable values like quantity, sales, and profit, ratio dimensions are the most appropriate choice.
