Ordinary arithmetic operations are meaningful

A) only with categorical data.
B) only with quantitative data.
C) either with quantitative or categorical data.
D) with neither quantitative or categorical data.

Ordinary arithmetic operations, such as addition, subtraction, multiplication, and division, involve quantitative data and can only be performed on numerical values. Categorical data is not quantitative and is not compatible with ordinary arithmetic operations. Therefore, the best choice is B, which states that arithmetic operations are only meaningful with quantitative data.
