What can SPSS Complex Samples do for your business?
IBM® SPSS® Complex Samples software can compute statistics and standard errors from complex sample designs by incorporating the designs into survey analysis. This solution helps you produce a more accurate picture by allowing subpopulation assessments to consider other subpopulations.
SPSS Complex Samples offers planning tools such as stratified, clustered or multistage sampling. It's designed to help you reach correct point estimates, predict numerical and categorical outcomes from nonsimple random samples and account for up to three stages when analyzing data from a multistage design. This module is included in the SPSS Premium package and available at an additional cost for the Base, Standard and Professional packages.
Improve accuracy of results
Increase the precision of your sample or ensure a representative sample from key groups. Employ multistage sampling to select a higher-stage sample.
Accelerate analysis, boost efficiency
Retain survey planning parameters. Publish data sets and reuse plans as templates. Select clusters or groups of sampling units to make surveys more cost effective.
Manage complex survey data
Display one-way frequency tables or two-way cross-tabulations. Build linear regression with ANOVA and ANCOVA. Estimate means, sums and ratios. And more.
Speed data and survey analysis
Use helpful wizards to specify how samples are defined and standard errors estimated; define schemes and draw samples. Select complex, probability-based samples from a population.
