13.5 cm? That means centimeter, which is a funny way of measuring water. But, let's say you are using gallons or liters, which are more standard approaches. Here is what I would do. I would plot the amount on the Y or vertical axis. It should probably go from 0 - 20 (Gallons) or whatever your unit is. On the X or horizontal axis, I would show the three different trials or tries. I would use a bar graph. It would probably look a little like this: | | + | + + | + + |------------------------- B S B S B S 1 2 3 B - bath S - shower Good luck!!
