The phrase "a correlation is achieved" is correct and usable in written English.
It can be used in contexts where you are discussing the establishment of a relationship or connection between two or more variables or factors.
Example: "After conducting the experiment, we found that a correlation is achieved between the amount of sunlight and plant growth."
Alternatives: "a correlation is established" or "a correlation is found".
Strong Level A correlations were achieved for fraction dissolved versus fraction absorbed.
This first calculation shows that a better correlation is achieved when considering an average secular variation computed over a five year time period (SV2) before the reference epoch, than when considering an average secular variation computed over a significantly longer time period (SV1).
The correlated result could be able to predict a trend of the factors and oil recovery as an empirical approach if a good correlation is achieved.
The result could be able to predict a trend of the factors-and-indicator if a good correlation is achieved.
The result could be extended to predict a trend of the factors-and-indicator relation potentially if a good correlation is achieved.
A good correlation is achieved between the experimental data and numerical predictions.
A comparative analysis of the results of the experimental pull-out tests results and those predicted from the analytical model indicates a satisfactory correlation is achieved between measured and predicted parameters.
A comparative analysis between the results of the experimental pull-out tests results and those predicted from the analytical model indicates a satisfactory correlation is achieved between measured and predicted effective bond length, verifying the validity of the new model.
Encouragingly, a reasonable correlation is achieved (R2 = 0.69), especially considering that the compounds screened by NMR and by docking are different.
Arguably, these conclusions could only be considered accurate once a statistically significant correlation is achieved by working with a larger sample group.
