correlate
This term is heavily associated with statistics and scientific research, carrying a clinical and objective tone. It describes a relationship where two variables move in tandem, though it specifically avoids claiming that one variable causes the other. Using this word instead of cause implies a cautious, analytical approach to data. As a noun, the word refers to a specific variable or factor that accompanies another. While it follows standard countability rules, it is almost exclusively used in academic or technical discourse to describe a co-occurring phenomenon rather than a simple association.
