SPSS (Statistical Package for the Social Sciences) is a tool for statistical analysis of survey data. SuperCHANNEL can import SPSS survey data and convert it to a SuperSTAR database.
A survey consists of a set of questions and the corresponding answers for each respondent. Each question will have a fixed set of possible answers.
The survey data must include:
- The questions.
- The allowable answers for each question.
- The survey responses for each question.
The .sps format allows for the survey data to be captured either in a single .sps file (which includes both the question definitions and the responses) or multiple files (with the question definitions in the .sps file and the response in a .dat file).
The following items are not currently supported by the SuperCHANNEL SPSS driver:
- Automatic creation of hierarchies.
- Date/Time handling.
Additionally, often SPSS creates a new value to substitute nulls and unanswered questions in the dataset. Typically this is stored as the new value -99.99. When this occurs within a metric/measurable field it will skew the data in SuperSTAR as these values will be used as true data points.
