Follow the numbered steps, then explain them in your own words
  1. QuantityHow many examples are there?
  2. QualityAre labels and content reliable?
  3. CoverageAre different situations included?
  4. EvaluationDoes it improve on new examples?

Data value depends on quality, coverage, and relevance to the task, as well as quantity.

Large amounts of repeated or incorrect data can strengthen bias and raise costs without adding useful information.

Adding suitable, representative examples of cases where a model often makes mistakes can be more helpful than repeating examples blindly.
