Data Representation. Rain barrel designs were tested for collected water and sediment concentration. Results were: no diverter, 180 L and 42 mg/L sediment; large diverter, 130 L and 8 mg/L; timed diverter, 165 L and 14 mg/L; screen only, 175 L and 31 mg/L. The goal is to keep sediment below 20 mg/L while collecting as much water as possible. Which redesign is best supported?
