Summary
The summary table reviews your analysis plan. The plan consists of one stage with a design of
one stratificationvariable and one cluster variable. With-replacement(WR) estimation is used,
and the plan is saved to c:\nhis2000_subset.csaplan. You can now use this plan file to process
nhis2000_subset.savwith Complex Samples analysis procedures.
Preparing for Analysis When Sampling Weights Are Not in the Data File
Aloanofficer has a collection of customer records, taken accordingto a complex design;
however,the sampling weights are not included in the file. This information is contained in
bankloan_cs_noweights.sav.For more information, see the topic Sample Files in Appendix A in
IBM SPSS Complex Samples 19.Starting with what she knows about the sampling design, the
officerwants to use the ComplexSamples Analysis Preparation Wizard to create an analysis plan
for this datafile so that itcan be processed by ComplexSamplesanalysisprocedures.
The loan officerknows that the records were selected in two stages, with 15 out of 100 bank
branches selectedwith equal probability and without replacement in the first stage. Onehundred
customers were then selected from each of those banks with equal probabilityand without
replacement in the second stage, and information on the number of customers at each bank is
included in the data file. The first step to creating an analysis plan is to compute the stagewise
inclusion probabilities andfinal sampl ing weights.
