A correlation coefficient of **0** indicates that there is **no linear relationship** between the two variables. This means that changes in one variable do not predict any consistent changes in the other variable. In other words, knowing the value of one variable does not provide any information about the value of the other. However, it is important to note that a correlation of 0 specifically means no *linear* relationship; there could still be a non-linear relationship that the correlation coefficient does not capture.

A correlation coefficient of 0 suggests no linear relationship between two variables.
