This is the average of all the means of all the questions within this battery section. To have a "weighted" average put in the weights. Note: This is only applicable to Matrix Type Questions: To Edit the weights goto :
Formula used: If X(n) is the mean for each of the questions in the battery and W(n) is the weight associated with each question then the weighted mean is calculated as follows:- W-Mean = [Sum(X(n) * W(n))] / Sum(W(n))
