Complex Samples Sampling Wizard
The agency willnow use its resources to collect current valuations for the properties selected in
the sample. Once those valuations are available, you can process the sample with Complex
Samples analysis procedures, usingthe sampling plan property_assess.csplan to provide the
sampling specifications.
Obtaining a Sample from a Partial Sampling Frame
A company is interested in compilingand selling a database of high-quality survey information.
The survey sample should be representativebut efficiently carried out, so complex sampling
methods are used. The full sampling design calls for the following structure:
Stage Strata Clusters
1Region Province
2District City
3Subdivision
In the third stage, households are the primary sampling unit, and selected households will be
surveyed. However, since information is easily available only to the city level, the company plans
to execute the first two stages of the design now and then collect information on the numbers of
subdivisionsand households from the sampled cities. The availableinformation to the city level is
collected in demo_cs_1.sav.Formore infor mation, see the topic Sample Files in Appendix A in
IBM SPSS Complex Samples 19.Note that this file contains a variable Subdivision that contains
all 1’s. This is a placeholder for the “true” variable, whosevalues will be collected after the first
two stages of the design are executed, that allows you to specify the full three-stage sampling
design now. Use the Complex Samples Sampling Wizardto specify the full complex sampling
design, and then draw the first two stages.
