Improve data preparation for more accurate results

IBM® SPSS® Data Preparation performs advanced techniques that streamline the data preparation stage of the analytical process to deliver faster, more accurate data analysis results. Analysts can choose from a completely automated data preparation procedure for the fastest results, or select from several other methods to help prepare more challenging data sets.

With this software, 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:

Automated data preparation

Automated Data Preparation helps users prepare data for analysis by automating tedious and repetitive tasks. This can improve analysis speed, predictive power and robustness, and enable users to include data that might be excluded in its raw state.

Automated data preparation

Validate data

The Validate Data tool helps identify suspicious and invalid cases, variables and data values in the active dataset. For example, a data analyst who provides a monthly customer satisfaction report to her client can use this feature to check for incomplete customer IDs, variable values that are out of range and combinations of variable values that are commonly entered in error.
