Data is the raw information from which statistics are created. Statistics provide an interpretation and summary of data and are the results of data analysis.  

Statistics

  • Statistical tables, charts, and graphs
  • Reported numbers and percentages in an article

If you are looking for a quick number to verify a claim, you want a statistic.  A statistic will answer "how much" or "how many" and will repeat a pre-defined observation about reality.  Statistics are the result of data analysis and usually appear in the form of a table or chart. 

Data

  • Datasets
  • Machine-readable data files, data files for statistical software programs

Data can be interpreted using statistical procedures to answer “why” or “how” and is used to create new information and knowledge.
