PREDICTION AND CORRELATION Correlation coefficients not only describe the relationship between variables; they also allow us to make predictions from one variable to another. Correlations between variables indicate that when one variable is present at a certain level‚ the other also tends to be present at a certain level. Notice the wording used. The statement is qualified by the use of the phrase “tends to.” We are not saying that a prediction is guaranteed‚ nor that the relationship is causal—but
