Jada is interested in studying whether her grass will feel softer if she mows the grass every 5 days or every 7 days. She guesses that if she mows it more often the grass will have sharp, ragged edges on it more often; she thinks waiting 7 days will produce softer grass. In the summer of 2020, she mows the grass every 5 days and asks people how her grass feels on their feet. In the summer of 2021, she mows the grass every 7 days. More people reported soft grass in 2021. 2. a)What is the independent variable for the experiment?
