Correlations can be described using everyday language that indicates how variables change together. For example, the statement "there is no relationship between height and weight" describes a zero correlation. Statements such as "usually, the taller someone is, the thinner they are" or "usually, the shorter someone is, the heavier they are" describe a negative correlation, where the two variables move in opposite directions. Conversely, a positive correlation is represented by a statement such as "as height increases, typically weight increases," indicating that both variables move in the same direction.
