Question

In the following situation, make recommendations as to the specific type of probability or nonprobability sampling approach to be used and the method(s) of selecting the sample. Justify your choice: A small Caribbean island relies heavily on tourist income. There is a need to develop a study so that an estimate can be provided each month as to: The number of tourists The length of stay Their activities Their attitudes toward some programs and activities. The plan is to conduct short interviews with respondents and to leave with them a short questionnaire to be completed and mailed after returning home. Several sampling plans are being considered: One is to generate a random sample of hotel rooms and to interview each occupant. Another involves sampling every nth person that passes a predetermined point in the city. Still another is to sample departing planes and ships. About six planes and three ships depart each day. Identify sources of sampling frame error for each of the plans above. Choose a sampling plan so that each month 500 tourists are obtained in the sample.

Explanation / Answer

In the given sampling plans available, the one where a lot of tourists would be available for interviews is the one that considers the hotels rooms and interviewing the occupants. This would reduce the inconsistencies of interviewing every nth person that passes a particular spot because you wouldn’t be aware of the tourist who would visit. Gather a list of all hotels where the tourists stays and be interviewing them. The flaw in this source is that you are likely to interfere with their schedules. Male versus female have different views concerning the appliances. The local newspapers should focus mainly on e-print in order to capture the attention of different age groups. The gift buyers on the other hand tend to select the elegance compared to buyers.
