WebJan 29, 2024 · If there is no overall pattern, then the covariance will be close to zero. This is because the positive and negative values will cancel each other out. At first, it might appear that the covariance is a sufficient measure of ‘relatedness’ between two variables. However, take a look at the graph below: Covariance = 0.00003.
In correlational research, you investigate whether changes in one variable are associated with changes in other variables.
