A set of data is plotted to create a scatterplot. The data is then linearized to form a quadratic model and then linearized to form an exponential model. The correlational coefficient for the linear model is .724. The correlational coefficient for the linearized quadratic model is .834. The correlational coefficient for the exponential model is .872. Based on these numbers, which model seems to be the best fit for the data? a The linear model b The quadratic model c The exponential model d A logarithmic model
