The phrase "actual correlation between" is correct and usable in written English.
It can be used when discussing the existence of a real or genuine relationship between two or more variables or factors.
Example: "The study aimed to determine the actual correlation between exercise frequency and mental health outcomes."
Alternatives: "real relationship between" or "genuine link between".
The surface with a long range order, i.e. single crystal Pd (1 0 0), was far more active that the corresponding polycristalline surface, suggesting an actual correlation between structure and reactivity, extremely relevant for performances.
At the same time, the actual correlation between the number of tweets a show's viewers generate and the ratings of those programs to data has been kind of tenuous.
However, the actual correlation between learning motivation and performance has not been accurately determined, and a precise definition of this construct is still lacking (Dörnyei 2001).
The next step is forecasting of the variation of the volume of sales in the oral healthcare sector up to 2030 based on the variation observed in the past (of the actual correlation between manifest demand and volume of sales).
There's no actual correlation between the Golden Globes and the Academy Awards, but perception often matters.
In this study, we are aiming at finding out the actual correlation between the two from patient's images.
What is the actual spatial correlation between RSN measured on slow envelope and HHM states?
The actual genetic correlation between populations, which is needed in the prediction formula, is in practice not known and depends on the traits and populations of interest.
The actual genetic correlation between BN and BW and additive variances for BN and BW in the parental populations were computed from the hybrid phenotypic values using a mixed model analysis.
This indicates that the deterministic formula can be used to estimate genetic correlations between populations (but does not provide information about the mechanism underlying this correlation); for example when the empirical accuracy is only 60% of the accuracy estimated assuming a genetic correlation of 1, the actual genetic correlation between populations is expected to be 0.6.
Error in rate estimation may also obscure actual correlations that exist between substitution rate and variation in particular traits.
