In which condition can comparison of decadal growth be wrong?
Answer and explanation
Correct answer: When data for one area cover ten years and data for another area cover five years
A valid comparison of decadal growth requires data for the same ten-year period in both areas. If one area is measured for ten years and another for only five years, the time intervals differ and the comparison can be misleading. Option B states a condition for a valid comparison, not an incorrect one. Exam tip: before comparing growth, always check that the time periods are identical.
