All were asked if they had ever used cocaine. Th e fi rst group was interviewed by telephone: 21% said Yes. In the group visited at home by an interviewer, 25% said Yes. Th e fi nal group was interviewed at home but answered the question on an anonymous form that they sealed in an envelope. Of this group, 28% said they had used cocaine.23 (a) Which result do you think is closest to the truth? Why?
