Question: A newspaper report on "regifting" claimed that most Americans engage in the practice of passing on unwanted gifts to others, since 323, or 64%, of 504 respondents admitted to regifting. A footnote to the description of the survey methodology mentions that 776 people responded to the survey, and only 504 qualified in the survey based on a screener question that was posed to filter out respondents who reported that they never received undesired holiday gifts. Should eBay (which conducted the survey as a promotional stunt to encourage selling unwanted gifts online) have screened out all the people who said they never received undesired holiday gifts? Does it make a difference in the reported percentage?
