Question
Which of the following issues should a data scientist be most concerned about when generating a synthetic data set?
- A. The data set consuming too many resources
- B. The data set having insufficient features
- C. The data set having insufficient row observations
- D. The data set not being representative of the population Correct
Explanation
A synthetic data set is only useful if it reproduces the statistical properties of the real population it stands in for; if it is not representative, any model trained or validated on it will be biased and will not generalize. Resource use, feature count and row count are practical concerns that can be tuned, since synthetic generation can produce as many rows or features as needed. Representativeness is the core risk.
