(a) Is there any problem of definition of the population? (b) What are the pros and cons of (1) the page, (2) the line, as a sampling unit? 1.2 A sample is to be taken from a list of names that are on cards (one name to a card) numbered consecutively in a file. Each name is to have an equal chance of being drawn in the sample. What problems arise in the following common situations? (a) Some of the names do not belong to the target population, although this fact cannot be verified for any name until it has been drawn. (b) Some names appear on more than one card. All cards with the same name bear consecutive numbers and therefore appear together in the file. (c) Some names appear on more than one card, but cards bearing the same name may be scattered anywhere about the file. 1.3 The problem of finding a frame that is complete and enables the sample to be drawn is often an obstacle. What kinds of frames might be tried for the following surveys? Have the frames any serious weaknesses? (a) A survey of stores that sell luggage in a large city. (b) A survey of the kinds of articles left behind in subways or buses. (c) A survey of persons bitten by snakes during the last year. (d) A survey to estimate the number of hours per week spent by family members in watching television.
