Suppose you were trying to decide which of two machines to purchase. Furthermore, suppose the length to which the machines cut a particular product part was important. If both machines produced parts that had the same average length, what other consideration regarding the lengths would be important? Why?
a.median length, avoiding outliers
b.variability, greater variation is more desirable
c. variability, less variation is more desirable
d.total length, which machine is better overall
