p. 20-21, #1-7

1. Total water volume used in three days: 802 L
2. Per person daily average use of water: 267 L
3. Check on sheet of paper
4. The range of the average daily personal water use within the class: 734 L
5. The mean: 447 L, The median: 468 L. The median seems to be more representative because there were many high numbers (for example 490 L) that were much higher than the average.
6. The average of the Buckley school students is most likely higher than the national average because we live in an advanced urban city. In addition, most residents of Los Angeles are in the upper/middle class allowing them the privileges of using more water than people in the lower classes.
7. The class average is closer than my personal average because my family is small. Usually, there are only two people living in my house and the average family is a family of four, which would require more water. My house  doesn't have a garden in the back or front yard, needing very little water for watering the lawn. Also, while the water diary was being written, my family wasn't home most of the time.
