from a past exam, I have the following question: Which type of sample survey would provide the most reliable data on the frequency of cinema-going of the population?
only one of 1,2,3,4 is "correct": 1) A house to house survey in the evening 2) A postal survey based on the electoral list 3) Interviewing outside the cinema 4) A household survey based on a population census or register ------- I can assume cost of the survey is not an issue right? then 2 is out, as 1 is better than 2 for reliability. 3 is out of the question as it does not cover the general population. So I think either 1 or 4 must be correct. But 4 is similar to 1, so what is the difference between a census and a Register??? and between a Register and a (i.e. electoral) List??? BTW a household survey is also presumably done from house to house, and not via post ? Thanks for your help. particularly, Dr. Paul Gardner for his past help in a similar question on finite sampling.
