Madam:
Sir:
I am currently teaching an introduction course in statistics, and a student asked me a question that confuses me. Let’s say we wish to compare the mean income of residents of two cities. We sample randomly residents in City A while we sample systematically in City B. Can we compare reliably the means of these cities? I would say yes as long as the samples represent well each of their respective cities. Do you agree with this answer?
Best regards,
