I'm having trouble determining the range movie tickets sold by looking at a histogram. I know you normally take the highest value represented and subtract the lowest value from it to get the range. However, when you have a histograme and the data set is represented like 2029, 3039, 4049 on the histogram would you determine the range by doing 49  20 = 29 or do you work it some other way? Thanks...

Depending on whether you want to emphasize or minimize the range, you could choose the end points or the midpoints, respectively.
