1. Total water volume (in liters): 9,436 L 
2. Average water use per person in one day: 524.16 L 
3. The photo above. 
4. The range is 1,493. 
5. Median: 579. Mean: 600. Mean is a better representation because we have large numbers and small ones so finding the average gives a better understanding of how much water each person used per day. 
6. In our class and in Los Angeles, we have many more lawns and plants that need everyday watering. Also, since it is summer and the weather gets very warm, we need more water. 
7. My answer for question 2, 524 L, is closer to the national average, 370 L because our classes average is 524 L. 

Discussion: I have realized that the range of our class is very large; the answer for why is because some of us have larger families than others and some of us use more water for watering our yards which uses a lot of water. The average of our class is very close to my families average, which means my family does not use too much or too little water compared to all 18 of us.
