IBM SPSS Data Preparation

With IBM® SPSS® Data Preparation, you can easily identify suspicious or invalid cases, variables and data values.
You can also view patterns of missing data, summarize variable distributions and more accurately work with algorithms designed for nominal attributes.

SPSS Data Preparation helps:

  • Automate the data preparation process—to eliminate complex, time-consuming manual data preparation.
  • Validate data without manual checks—to perform faster, more accurate data validation.
  • Prevent outliers from skewing analysesto automatically detect anomalies that could corrupt results.
