A girlscout troop leader wondered whether providing an incentive to whomever sold the most girlscout cookies would have an effect on the number cookies sold. She provided a big incentive to one troop (trip to Hawaii), a lesser incentive to a second troop (bicycle), and no incentive to a third group, and then looked to see who sold more cookies. Troop 1 (Hawaii) 6 5 9 4 6 Troop 2 (bicycle) 6 8 5 4 2 Note: 5 girls in each troop Troop 3 (nada) 0 4 0 1 0 x = 6 x = 5 x = 1 What if we want to replicate study but add another group (level) to our independent variable
