This storyboard does not have a description.
If I use Pantene shampoo versus Suave, then my hair will grow a lot quicker.
I am about to be home to start the experiment, but I have to remember the controls: the hair type, how much shampoo is used, and the water temperature.
Also, that the independent variable is the type of shampoo, and that the dependent variable is the hair growth.
My friend, Martha, is the control group because she will wash her hair only with water for a week. While Erin and I are the experimental group. She will use Pantene and I will use Suave.
Our data shows that Erin's hair was 11 inches, and mine was 12, while Martha's hair stayed the same length.
My hypothesis was incorrect because my hair was longer, and I used Suave.
