Arithmetic operations provide meaningful results for variables that
A) use any scale of measurement except nominal and ordinal.
B) appear as non-numerical values.
C) are quantitative.
D) have non-negative values.

Question

Quizplus · Accepted Answer

Arithmetic operations involve numerical values, so variables that are quantitative (measured on a numerical scale) are the only ones that provide meaningful results through arithmetic operations. Nominal and ordinal variables are measured on non-numerical scales, and variables with negative values can still be quantitative, but may require additional considerations in the arithmetic operations performed. Non-numerical values would not provide meaningful results through arithmetic operations.
