Perform the high/low method using the following data from Herman Miller's 10-k report. You'll see that the normal calculations for the high-low use changes in activity levels (number of units produced) to perform high-low calculations. This isn't realistic for this data set, this company produces many different types of products, and activity information is sometimes difficult to find. Instead of using a volume-type number for activity, (number of units produced/sold) use revenue dollars. So the ratio should be something like this: (Operating expenses high year Operating expenses low year)/ (Revenue high year Revenue low year).
