Statistical Analysis of Academic Performance: Correlation, Prediction, and DataComparison1.Correlation, Scatterplots, and Predictiona)Which relationship is stronger, the relationship between GPA and AGE or therelationship between GPA and SAT score? Be sure to include all appropriate measuresand explain and defend your answer. Is this result what you would expect, why or whynot?Correlation between GPA and AGE0.233751Correlation between GPA and SATscore0.320311Looking at the correlation values we see that the correlation between GPA and SAT is more thanGPA and AGE. Hencethe relationship between GPA and SAT score is stronger than therelationship between GPA and AGE.The result is as expected as GPA and SAT both being relatedto scores are more correlated to eachother than AGE.b)Create and paste in a scatterplot that compares Final Exam Score and Project Score.What is the correlation (r-value)? How would you describe the correlation (positive,negative, strong, weak, medium, none)? Include the “trendline” and “equation of thetrendine” as part of your scatterplot.The correlation (r-value) = sqrt(.1429) = .378y = 0.2836x + 54.747R² = 0.1429020406080100120020406080100120Project scoreFinal exam score
