What term describes a correlation between two variables?

• A. Simple correlation
• B. Partial correlation
• C. Bivariate correlation
• D. Canonical correlation

Answer: (C)

A correlation between two variables is described as a bivariate correlation. This term highlights that the relationship involves exactly two variables at a time. Partial correlation, on the other hand, looks at the association after accounting for a third variable, and canonical correlation examines relationships between two sets of variables. While simple or Pearson correlation is commonly used for two variables, the standard descriptor in many contexts is bivariate correlation.
