What to Focus On

  • Data cleaning removes or corrects errors and inconsistencies.
  • Clean data must be in a format suitable for analysis.
  • Dirty data contains many errors or has not been cleaned.
  • Missing values are a type of dirty data.
  • Outliers are values far outside the norm.
  • Duplicates can distort analysis by overrepresenting records.
  • Data quality means following required rules and formats.
  • Completeness means all required values are known.
  • Consistency can be checked across systems, sources, or latest data.

Common Mistakes to Avoid

Data cleaning means making the data look neat, not changing its meaning or quality.

Missing values are harmless because blank cells do not affect results much.

Outliers are always mistakes and should always be removed.
