Častá chyba:
Learners often think "correlation" means the same as "cause" or "causation". However, correlation only shows that two things change together, not that one makes the other happen. Also, learners sometimes use the wrong structure, saying *"the correlation of A and B"* instead of the more natural *"the correlation between A and B"* in general writing.

Častá chyba:
Learners sometimes confuse the everyday idea of a "connection" with the strict statistical meaning of a correlation value. They may also think that any relationship must have a high correlation, forgetting that correlation usually describes linear relationships and can be low even when a curved pattern exists.
