If your data analysis includes a line graph(s) you must interpret the trend(s) of the data.  For example, as the independent variable increases the dependent variable increases/decreases/stays the same?

example:  As the length of the lever increased the amount of force needed to lift the concrete block decreased.

example: As the amount of water increased from 5 mL a day to 35 mL a day the height of the plant increased, but as the amount of water increased from 35 mL to 100 mL a day the height of the plant decreased.
