Quantity Bias Study 2

We presented two scenarios to 398 participants. One scenario where the total number of items varied uniformly from 2 to 21, with a single item cheaper at the second store. The other scenario where the total number of items varied uniformly from 6 to 25, with 5 items cheaper at the second store. Held constant was the time to the second store (5 minutes), cost of all items at the first store ($50), and the savings by buying the cheaper items at second store ($5). To make sure subjects read the question we required them to repeat back each of the variables first, then we asked them how likely they were to go to the second store. Participants with 3 or greater correct check answers are supplied here.
