Data Management

 

Whether scanned from paper survey form, entered by interviewers into a database, or collected from web-based surveys, our experts can prepare and convert your data into a structure and form needed for analysis. Our examination of the data includes:

  • Performing data verification and cleaning, which helps ensure your analytical results are accurate.
  • Detecting and fixing discrepancies in databases.
  • Creating “codebook” information, which includes variable names, variable formats and descriptive variable labels.
  • Setting-up multiple-item indices and scales, which combine multiple indices into a single, multiple-item index.
  • Filling in missing data if necessary. By replacing missing data values with estimates, you ensure better summary statistics.
  • Weighting data if needed to match the demographics of the target population.
