## cor·re·la·tion

(kôr′ə-lā′shən, kŏr′-)
n.
1. A relationship or connection between two things based on co-occurrence or pattern of change: a correlation between drug abuse and crime.
2. Statistics The tendency for two values or variables to change together, in either the same or opposite way: As cigarette smoking increases, so does the incidence of lung cancer, indicating a positive correlation.
3. An act of correlating or the condition of being correlated.

[Medieval Latin correlātiō, correlātiōn- : Latin com-, com- + Latin relātiō, relation, report (from relātus, past participle of referre, to carry back; see relate).]

## correlation

(ˌkɒrɪˈleɪʃən)
n
1. a mutual or reciprocal relationship between two or more things
2. the act or process of correlating or the state of being correlated
3. (Statistics) statistics the extent of correspondence between the ordering of two variables. Correlation is positive or direct when two variables move in the same direction and negative or inverse when they move in opposite directions
[C16: from Medieval Latin correlātiō, from com- together + relātiō, relation]
