Question:
questionnaires. These give information on who is watching TV and what program. What are the limitations of this questionnaire method?
Answers:
Well, questionnaires might be very subjective, as the person filling it up might not be giving his true opinion at that point in time.
Also, neilsen can't get every tv viewer to fill up the questionnaire - that would be impossible. so they take a sample from say 1% of the total population and use their answers as a reflection of the whole population. So the limitation here is, does that sample size truely reflect the whole population?
