Complex Samples Sampling Wizard
The agency will now 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, using the sampling plan property_assess.csplan to provide the
sampling specifications.
Obtaining a Sample from a Partial Sampling Frame
A company is interested in compiling and selling a database of high-quality survey information.
The survey sample should be representative but efficiently carried out, so complex sampling
methods are used. The full sampling design calls for the following structure:
Stage Strata Clusters
1
Region Province
2
District City
3
Subdivision
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
subdivisions and households from the sampled cities. The available information to the city level is
collected in demo_cs_1.sav. For more information, see the topic Sample Files in Appendix A in
IBM SPSS Complex Samples 1 9. Note that this file contains a variable Subdivision that contains
all 1’s. This is a placeholder for the “true” variable, whose values 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 Wizard to specify the full complex sampling
design, and then draw the first two stages.
