Evelyn claims that out of the 1000 surveys that she sent by mail to random addresses around the
city, only 121 were returned. What is an appropriate comment regarding this response rate ?
O The sample could be biased because there was no monetary incentive to respond
O No concern because more than 10% have responded
O The surveys were sent to random addresses so the sample can be considered representative
There is potential bias if the subjects responding have a systemic characteristic (relevant to the study) not
shared by non-respondents
