Sampling Design Minicase: A market researcher is proposing a survey questionnaire for a private golf country club that is contemplating several changes in its layout to make the golf course more of a championship calibre. The researcher is considering three different sample designs as a way to draw a representative sample of the club's golfers. The three alternative designs follow: a. Station an interviewer at the first-hole tee on one day chosen at random, with instructions to ask every 10th golfer to fill out a self-administered questionnaire. b. Put a stack of questionnaires on the counter where golfers check in and pay for their golf carts. There would be a sign above the questionnaires, and there would be an incentive for a "free dinner in the clubhouse" for three players who fill out the questionnaires and whose names are selected by a lottery. c. Using the city telephone directory, a random dialing procedure would be used. With this procedure a random page in the directory would be selected, and a name on that page would be selected, both using a computerized random number generator (RNG). This system would be applied to that name and every name listed after it until 1,000 golfers are identified and interviewed by telephone. Assignment: . Describe the representativeness/validity and other issues associated with each of the three sampling methods. Identify the sampling method that is being used in each case. Which sample method do you recommend using and why
