Definition: "BVD" stands for "Background Variable". It's a term in statistics that describes how changes to one variable (in this case, the baseline or control variable) affect other variables (in this case, the outcome variable). When a researcher uses BVD, they are looking at how changes to some independent variable impact another dependent variable. For example, if an experiment is designed to test whether drinking more coffee affects concentration on a cognitive task, it could be used to test whether baseline coffee consumption impacts cognitive performance.
The term "BVD" is often used when researchers are studying the relationship between two or more variables, and they want to know how those changes affect a third variable.
