Assertion (A): Classing the data for a choropleth map inevitably discards information.
Reason (R): Every value within a class is drawn with the same tone regardless of its exact size.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both hold, and the reason gives the mechanism: once a range is assigned one shade, the differences inside that range become invisible. The compensation is a map the reader can actually decode, which an unclassed version often is not.
