  1. Car price vs. Student GPA:Is there a correlation? Group 9 Traci Mecham Kristina Hight Jonathan Fisher MorgaineAbawi Kiffen Davis

  2. For Salt Lake Community College students who own a car, is the price for their car related to their GPA?

  3. Data Collection • Sampling Method: Simple Random • Strata: Jordan, Taylorsville and South City Campuses • 50 samples from each campus. • Price of car recorded as price paid when purchased and current GPA was used.

  4. Price of Car Histogram • Well over half of the students had cars in the < $20,000 range • Only a very small number had cars costing over $30,000

  5. As you can see the box plot is skewed heavily to the right, due to the high number of relatively moderate priced vehicles in conjunction with a few in the higher price range. Car Price Box Plot

  6. Price of car stats The mean price of a car was $12,523 while the range was over $50,000

  7. GPA Histogram • The ranges with the most students were • 3.0-3.24 • 3.5-3.74 • The majority were over 3.0.

  8. This box plot is skewed to the left due to infrequency of students with a low GPA GPA Box Plot

  9. The mean GPA was 3.36, and ranged from 2.0 to 4.0 Grade Point Average Stats

  10. Avg. Car Price, GPA, Sample Size • The bar series represents the Avg. Car Price of students with the specified GPA • The line series represents the number of samples collected for the GPA • The error bars represents the standard deviation of Car Prices across all sample GPAs

  11. Car Price, GPA - Scatterplot • Each plot point on the graph represents a survey sample • Samples are distributed by the Car Price on the Y-axis and the GPA on the X-axis

  12. RESULTS Our study was unable to find any correlation between the GPA and price of vehicle for Salt Lake City Community College students and concludes that the two variables appear to be unrelated
