The coefficient of agreement in determining product preferences

Abstract

The coefficient of agreement is most appropriately used in conjunction with the method of paired comparisons. It enables the experimenter to measure the degree and test the significance of agreement among observers as to their preferences for a series of items offered for consideration. Unlike the method of ranks, this technique does not depend upon any assumptions of linearity in the variate being measured. Because of this fact, the method is advisable when subjective times such as preferences for food, clothes, and so on are measured. It can also be readily used in the construction and testing of attitude and opinion scales. In this report the preferences of a jury of observers for four types of ice cream were determined by the paired comparisons method and the results tested by using the coefficient of agreement.
