Group 9 Traci Mecham Kristina Hight Jonathan Fisher Morgaine Abawi Kiffen Davis For Salt Lake Community College students who own a car, is the price for their car related to their GPA? 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. Well over half of the students had cars in the < $20,000 range Only a very small number had cars costing over $30,000 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. The mean price of a car was $12,523 while the range was over $50,000 The ranges with the most students were 3.0-3.24 3.5-3.74 The majority were over 3.0. This box plot is skewed to the left due to infrequency of students with a low GPA The mean GPA was 3.36, and ranged from 2.0 to 4.0 $16,000.00 60 $14,000.00 50 $12,000.00 40 $10,000.00 $8,000.00 30 $6,000.00 20 $4,000.00 10 $2,000.00 $0.00 0 2.25 • • • 2.5 2.75 3 3.25 3.5 3.75 The bar series represents the Avg.
