Incorporate sample design into survey analysis
- Increase the precision of your sample or ensure a representative sample from key groups.
- Select clusters or groups of sampling units to make your surveys more cost-effective.
- Employ multistage sampling to select a higher-stage sample.
Retain survey planning parameters for future use
- Publish public-use data sets that include your sampling and analysis plans.
- Use published plans as a template in order to save decisions made when creating the plan.
- Make plans available to others in the organization so they can replicate results or pick up where you left off.
Manage complex survey data
- Display one-way frequency tables or two-way cross-tabulations and associated standard errors, design effects, confidence intervals and hypothesis tests.
- Build linear regression, analysis of variance (ANOVA) and analysis of covariance (ANCOVA) models.
- Estimate means, sums and ratios, and compute standard errors, design effects confidence intervals and hypothesis tests for samples drawn by complex sampling methods.
- Perform binary logistic regression analysis and multiple logistic regression (MLR) analysis.
- Apply Cox proportional hazards regression to analysis of survival times.
Use an intuitive interface and helpful wizards
- Use the Analysis Preparation Wizard to specify how the samples are defined and how standard errors should be estimated.
- When creating your own samples, use the Sampling Plan Wizard to define the scheme and draw the sample.
- Use the IBM SPSS Complex Samples Selection (CSSELECT) procedure to select complex, probability-based samples from a population while mitigating the risk of over-representing or under-representing a subgroup.
