Bryan is interested in studying whether his grass will feel softer if mows his grass every 5 days or every 7 days. He guesses that if he mows it more often the grass will have sharp, ragged edges on it more often; he thinks waiting 7 days will produce softer grass. In the summer of 2011 he mows the grass every 5 days and asks people how his grass feels on their feet. In the summer of 2012, he mows the grass every 7 days. More people reported soft grass in 2012. Answer the following questions about this experiment.

a. What is the independent variable for the experiment

b. What is the dependent variable for the experiment?
