coefficient
(redirected from correlation coefficient)

    Also found in: Dictionary/thesaurus, Medical, Financial, Encyclopedia, Wikipedia 0.01 sec.

coefficient

Number part in front of an algebraic term, signifying multiplication. For example, in the expression 4x2 + 2xy − x, the coefficient of x2 is 4 (because 4x2 means 4 × x2), that of xy is 2, and that of x is −1 (because −1 × x = −x).

In general algebraic expressions, coefficients are represented by letters that may stand for numbers; for example, in the equation ax2 + bx + c = 0, a, b, and c are coefficients, which can take any number.
