MM207 Unit 9 Final Project
Assignment and Template
1. Correlation, Scatterplots, and Prediction
a) Which relationship is stronger, the relationship between GPA and AGE or the
relationship between GPA and SAT score? Be sure to include all appropriate measures
and explain and defend your answer. Is this result what you would expect, why or why
not?
Correlation between GPA and AGE 0.233751
Correlation between GPA and SAT score 0.320311
Looking at the correlation values we see that the correlation between GPA and SAT is more than
GPA and AGE. Hence the relationship between GPA and SAT score is stronger than the
relationship between GPA and AGE. The result is as expected as GPA and SAT both being related
to scores are more correlated to each other 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 the
trendine” as part of your scatterplot.

The correlation (r-value) = sqrt(.1429) = .378
The correlation is positive hence project score and final score both have similar
behavior, that is both of them increases or decreases together. But the strength of the
relationship between the two is week as the r-value is close to 0 than 1.
c) Using the equation from your above scatterplot trendline, predict (estimate) the Project
score for a person who gets a final exam score of 82. Show all of your work.
y = 0.2836x + 54.747
So, the project score of a person whose final exam score 82 is
y = 0.2836*82 + 54.747
= 78.002
2. Comparing and Describing Data
For the Final Exam Score and then for the Project Score, calculate the mean, median,
mode, range, standard deviation, and variance. (Hint: remember to use the sample std dev
and sample variance).
