Sat Scores Vs. Acceptance Rates Essay

778 words - 3 pages

The experiment must fulfill two goals: (1) to produce a professional report of your experiment, and (2) to show your understanding of the topics related to least squares regression as described in Moore & McCabe, Chapter 2. In this experiment, I will determine whether or not there is a relationship between average SAT scores of incoming freshmen versus the acceptance rate of applicants at top universities in the country. The cases being used are 12 of the very best universities in the country according to US News & World Report. The average SAT scores of incoming freshmen are the explanatory variables. The response variable is the acceptance rate of the universities.I used September 16, 1996 issue of US News & World Report as my source. I started out by choosing the top fourteen 'Best National Universities'. Next, I graphed the fourteen schools using a scatterplot and decided to cut it down to 12 universities by throwing out odd data.A scatterplot of the 12 universities data is on the following page (page 2)The linear regression equation is:ACCEPTANCE = 212.5 + -.134 * SAT_SCORER= -.632 R^2=.399I plugged in the data into my calculator, and did the various regressions. I saw that the power regression had the best correlation of the non-linear transformations.A scatterplot of the transformation can be seen on page 4.The Power Regression Equation isACCEPTANCE RATE=(2.475x10^23)(SAT SCORE)^-7.002R= -.683 R^2=.466The power regression seems to be the better model for the experiment that I have chosen. There is a higher correlation in the power transformation than there is in the linear regression model. The R for the linear model is -.632 and the R in the power transformation is -.683. Based on R^2 which measures the fraction of the variation in the values of y that is explained by the least-squares regression of y on x, the power transformation model has a higher R^2 which is .466 compared to .399. The residual plot for the linear regression is on page 5 and the residual plot for the power regression is on page 6. The two residuals plots seem very similar to one another and no helpful observations can be seen from them. The outliers in both models was not a factor in choosing the best model. In both models, there was one distinct outlier which appeared in the graphs.The one outlier in both...
