    What method did you use to select the restaurants to ensure the selection was random?

    Umm, I just thought of restaurants I knew. Should I have done something else?

    One way to make a random sample of restaurants is as follows: 1. Make a list of all the restaurants in a city ensuring that the chosen city has a number of restaurants much greater than 15. 2. Assign a unique number to each restaurant. For example if there are 100 restaurants, number them 1 to 100. 3. Use a table of random numbers to select 15 restaurants. The above method is designed to ensure that each restaurant has an equal probability of being chosen, therefore meeting the requirement of a random selection.
