Data correlation
Hi everyone,
I have a question about correlation between two data. Here is my sentence:
It is believed that the best correlation between porosity, permeability and pore throat size is established in 35 % mercury saturation.
I am not sure about the “established”. Obtained, found or something else?
Thanks

- It does not make any sense.

- Correlation measures the degree to which two variables track each other.
