Which of the following refers to a correlation between two variables?

A) bicorrelate
B) bivariate
C) two-way variance
D) two-way analysis

Bivariate refers specifically to the correlation between two variables. "Bicorrelate" is not a commonly used term in statistics. "Two-way variance" is a term used in ANOVA (analysis of variance) to describe the variability due to two or more factors. "Two-way analysis" could refer to a variety of statistical techniques that involve two variables or factors, but does not specifically indicate a correlation between them.
