Zoo Attendance.

The Cincinnati Zoo and Botanical Gardens had a record attendance of 1.87 million visitors in 2017 (Cincinnati Business Courier website). Nonprofit organizations such as zoos and museums are becoming more sophisticated in their use of data to improve the customer experience. Being able to better estimate expected revenue is one use of analytics that allows nonprofits to better manage their operations.

The file below contains sample data on zoo attendance. The file contains data on 125 visits by families to a zoo: amount spent, size of the family, the distance the family lives from the zoo (the gate attendee asks for the zip code of each family entering the zoo), and whether or not the family has a zoo membership (1 = yes, 0 = no).
