Project Topics from the past

Here are some projects groups have done in previous semesters. I hope these will spark your imaginations as you plan your own projects.

PROJECT 1: Comparing Two Quantities

• People's height versus weight (DON'T do this one. I am really tired of it.)
• Price of a magazine versus the number of pages
• Mileage of a car versus its age
• Air temperature versus relative humidity
• Closing values for AMEX versus Dow Jones
• Cost of an airline ticket versus miles of the flight
• Playing time for a Bellarmine women basketball player versus points scored
• Per capita income versus life expectancy in various countries

PROJECT 2: Estimating a Mean

• Average number of siblings a Bellarmine student has
• Average length of time it takes a female Bellarmine dorm student to get ready in the morning
• Average amount of cash carried by employees at (one of the student's workplace)
• Average number of pairs of tennis shoes owned by Bellarmine dorm students
• Average number of miles on a Bellarmine student's car
• Average number of emails in a student's Inbox
• Average E.R.A. of major league baseball pitchers

PROJECT 3: Testing a Hypothesis

• Bellarmine dorm students spend more than $30 weekly at restaurants.
• Male Bellarmine students in Newman Hall prefer Bud Light over Miller Lite.
• Average out-of-state tuition for universities in California is greater than $5000.
• Bellarmine dorm students spend more than $200 on spring break.
• Bellarmine women have an average shoe size greater than 7.5.
• The average N.B.A. player is more than 76 inches tall.

Here are a couple suggestions as you plan Projects 2 and 3:

• Be careful about the population you pick. With a large population, such as all residents of Louisville, it will be hard to get a truly random sample. For these projects it is better to think small.
• Plan your sampling method ahead of time.
