I'm currently stuying the values of a conversion variable - and would like to calculate the mean value. I've already done this with the visits, but this is diferent since I can't use any dimension on the Calculated metrics tool. I just can get the Instances of that dimension, but the mean has nothing to do with the mean of my dimension values :
Is this possible ? to multiply each value of a dimension by the number of instances ? Or I have to extract via the Datawarehouse and do the calculus with another tool ?
You can't use a dimensions value as part of a calculated metric, instead you can change your implementation to set the value of the dimension to a custom event as well, and the use that event to make your calculations on.
