Writing a Data Cleaning Report

Reporting your data-cleaning efforts is essential for tracking alterations to the data. Future data mining projects will benefit from having the details of your work readily available.

Task List

It's a good idea to consider the following questions when writing the report:

• What types of noise occurred in the data?
• What approaches did you use to remove the noise? Which techniques were successful?
• Are there any cases or attributes that could not be salvaged? Be sure to note data excluded due to noise.
