A negative correlation is a statistical relationship between two variables that move in opposite directions. Some common synonyms for negative correlation include inverse correlation, anticorrelation, and negation correlation. Inverse correlation is often used to describe a situation where one variable increases while the other decreases, and vice versa. Anticorrelation is similar to inverse correlation but suggests a more binary relationship where the two variables are mutually exclusive. Negation correlation is a less common term that simply means the two variables have an opposite relationship. It is important to understand these synonyms in order to accurately describe statistical findings and relationships between variables.
