9. Summary

We have seen that by asking some simple questions, we can improve the quality of data and information. These are

  • Is it complete (enough)
  • Is it accurate
  • Is it unbiased
  • Is the data plausible

We have seen that errors can easily creep in at each point in the stream of data. This includes

  • At the point of capture
  • Input
  • Processing
  • Transmission

But there are a number of method we can use to improve things such as using multiple sources, more than one person checking the data, using automatic tools such as spell checkers and data validation.
