Q DATA DAY 4 Your fourth Data Day is a Data Challenge. You are to work on this by yourself. Collaboration is strictly prohibited. In this Data Challenge, you are going to use the Data Set called Student Survey to determine the answer to this question: Is GPA related to the number of piercings? That is, do students with more (or fewer) piercings have better grades. Use any of the techniques you have learned in this class to make your case (justify your choices). Present all your data and then write a one page article for the school newspaper giving your findings.
