Which store has a more varied data? (Show the needed math work) Range = Highest Value − Lowest Value Interquartile Range = Quartile 3 − Quartile 1

• Store V, based on RANGE

• Store S, based on INTERQUARTILE RANGE

• Both stores have equally varied data, based on RANGE

• Both stores have equally varied data, based on INTERQUARTILE RANGE
