The tendency for the values of two variables to move in a predictable and related way is known as correlation. This means that as one variable increases or decreases, the other variable also tends to increase or decrease. Correlation is measured between -1 and +1, with a correlation coefficient of 0 indicating no relationship, a positive correlation coefficient indicating a positive correlation, and a negative correlation coefficient indicating a negative correlation.
