Drake Glau Posted January 4, 2011 Report Share Posted January 4, 2011 Hmm, something related maybe. Give them a hypothetical situation where they have $100 (or whatever number/currency you so choose) and then give them a few categories from which they can buy stuff from.For exampleYou have $100 and are going to the mall and can spend any amount of the $100 on these categoriesEntertainment:Food:Clothes:Technology:You would need to keep something constant of course, maybe age, gender, grade level, anything else you can think of. From this you could find relations between your constant (the age or whatever) and where they would hypothetically spend the most money.

Drake Glau Posted January 5, 2011 Report Share Posted January 5, 2011 You only need to do two calculation, I would certainly run a chi squared test, after that it's up to you. You can do pearson's coefficient, coefficient of determination (they kind of go together), you could always figure out a line too. All up to you, you just need 2 mathematical calculations included for full points in that section. Reply Link to post Share on other sites More sharing options...
