In mathematics,  a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
The difference between factors and coefficient is very distinct. A  factor is a quantity which is multiplied with another to give a  particular number as the result. A coeff â¦ icient on the other hand is  a multiplier that measures property. 3 people found this useful.n the other hand, if you interchange variables X and Y in the calculation of correlation coefficient you will get the same value of this correlation coefficient. (5) The same underlying distribution is assumed for all variables in linear regression.
