Correlation is typically represented by the variable r, which quantifies the strength and direction of a linear relationship between two variables. A value of r = 0 indicates no linear correlation (what we have here). However, r is only defined when variability exists in both variables. If there's insufficient data or constant values, r would be cannot be determined. But since we have a large set of diverse data, we can confidently say r = 0.
