In the chapter 4 project, my partner and I collected and analyzed data. We wanted to know if the number of total wins and the number of national titles won had any correlation. To find this out, we went to ESPN to collect our data. We looked at 50 different teams and recorded how many total wins and how many national championships won. We typed all the data into the calculator. Our graph showed the explanatory variable on the x axis, which was the number of wins, and the response variable, on the y axis, which showed the number of national titles. This gave us a positive moderate correlation. Our correlation coefficient r was .612. If our coefficient r was .8 or .9 it would have had stronger correlation. This project helped us practice skill to find explained and unexplained variables, interpols, and extrapolation.
