Answered by The Community. Making the world better, one answer at a time. 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 coefficient on the other hand is a multiplier that measures property.he difference is that the point-biserial  correlation is used when the dichotomous variable is a true or  discrete dichotomy and the biserial correlation is used with an  artificial dichotomy. . 2 people found this useful.
