In statistics, bivariate data consist of which of the following?

• A. Pairs of values for two different variables measured on the same individuals
• B. Three or more variables measured on the same individuals
• C. Values of a single variable measured on different individuals
• D. A single value measured repeatedly over time

Answer: (A)

Verified step by step guidance

1. Understand the definition of bivariate data: it involves data collected on two different variables.
2. Recognize that bivariate data consists of pairs of values, where each pair corresponds to measurements of two variables taken from the same individual or unit.
3. Distinguish bivariate data from univariate data, which involves only one variable, and multivariate data, which involves three or more variables.
4. Note that repeated measurements of a single variable over time do not constitute bivariate data, as only one variable is involved.
5. Conclude that bivariate data specifically refers to pairs of values for two different variables measured on the same individuals.
