Your task is to interview a representative sample of attendees to a large concert.
The schedule includes 200 live concerts featuring all types of entertainers. Since neither the number of attendees nor their descriptive characteristics are known in advance, you decide on non-probability sampling.
Based on prior data, you can calculate the number of tickets that will be available for each of the 200 concerts and the number of possible attendees for each concert.
Attendance data from the past two years gives you gender data on the attendees.
1. How would you conduct a reliable non-probability sample?
2 How will you mitigate your conclusions given that the sample was not selected randomly?
