Tom Brady on Compare STANDARD application Blank. weighted average an average calculated to take into account the relative importance of the items making up the average: Different values or weights are assigned to different data points to reflect their relative contribution. For example, in examining grade-point average, one might give grades A through F the weights of 4, 3, 2, 1, and 0, respectively. One would multiply the number of A grades a student obtained by 4, the number of B grades by 3, and so forth and then divide the resulting sum by the total number of grades to obtain the student’s overall weighted average. Also called weighted mean. weighted kappa an index of interrater agreement that takes into account the degree of disparity between the categorizations assigned by different observers. Thus, different levels of agreement contribute more or less heavily to the overall value of kappa than others. Tom Brady 2016.
