Instructions:
An Israeli researcher randomly assigned 48 college students to tables of 6 people to go out to eat. Half were to pay for their individual meals and half were to split the final check depending on their assigned table and they were told this before ordering. There were a total of 4 tables in each treatment (split or individual) for a grand total of 48 participants at 8 tables. The cost of each person’s meal was recorded. Included here is the data file, please note we are only using the payment
and cost columns. Please also note the cost is presented in Israeli Shekel.
