Math 10 Lab 2 – Cross-tabulation and Two Way Tables In 2016, researchers from Harvard Business School conducted an experiment on the online rental company Airbnb to explore if there is racial discrimination. Airbnb allows owners (hosts) to rent out all or part of their properties to guests. Renters (guests) create a profile on Airbnb and hosts are allowed to accept or reject potential renters. The researchers created 20 profiles on Airbnb that were identical in every way except for name. Based on hospital birth records from 1974 to 1979, 10 "distinctively white" names were chosen and 10 "distinctively African-American (black)" names were chosen. Each of these groups had 5 male and 5 female names. No photos were added to these 20 profiles. From 5 randomly selected and geographically dispersed metropolitan areas, the researchers using these 20 profiles attempted to rent approximately 6400 similar properties listed on Airbnb. Each rental was for dates about two months in the future. The Minitab file contains 6269 records recreated from this study: data for name, race, gender, and whether or not the applicant was accepted by the host. 1. For the variables Name , Race , Gender and Accepted , identify the explanatory variables and the response variables. Explanatory Variables: Name, Race, and Gender Response Variables: Accepted 2. What lurking variables did the researchers control for? Profile variables such as age, the number of reviews, picture, etc. As well as the listings: day of the listing and type of listing 3. You can make a stacked bar 100% graph: MINITAB>graph>bar graph and then select the stack option. Choose the three variables Race, Gender, Accepted, then click Chart Options and choose Show Y as a Percent and Within categories at level 2 . Create the graph and paste it here. Analyze and explain what this graph is showing. (If you are using Minitab Express or Mac, make clustered bar graphs instead)
