Answer: (iv) Data transformation

Data mining is historically also known by several near-synonyms:

  • Knowledge extraction (extracting patterns/knowledge from data)
  • Data archaeology (digging through historical data for insight)
  • Data exploration (exploratory analysis of a dataset)

All three of these describe the act of mining itself. Data transformation, however, is a preprocessing step (converting/normalizing data into a suitable form) that happens before mining — it's not itself a synonym for or activity that defines data mining, making it the odd one out.
