From page 137...
... To define a sample of these organizations, a list of all of them would ideally be developed, as -- unlike air passengers -- they cannot be sampled as they make use of the airport. Development of such a list can be difficult, if not impossible, and the surveyed population is often restricted to businesses for which contact information is readily available.
From page 138...
... For example, in airport awareness studies, should all businesses be treated equally, or should large businesses be given more weight and, if so, by how much? Similar issues come up in other types of area business surveys for questions not scaled by the size of the business or level of air travel.
From page 139...
... Where stratified sampling is used, the proportion of businesses in each stratum (group) will generally not be the same for all strata.
From page 140...
... 140 Guidebook for Conducting Airport User Surveys Questions asked when surveying businesses are very different from the questions used in other airport user surveys, which typically survey individuals. In medium- and large-sized organizations, for example, uncertainty can arise over which office or department should be responding to the survey.
From page 141...
... The budget for Internet surveys of area businesses will include survey design and planning, including the development of a list of businesses; questionnaire design, testing and loading onto a survey website; follow-up of non-respondents; data checking and analysis; and reporting and presentation of findings. (See Chapter 2 for a more detailed discussion of the budget.)
