In systematic sampling the samples drawn ........................ .

  • A.Are not overlapping
  • B.May be overlapping
  • C.Are non-random in nature
  • D.Are not proper representative

Answer: A

In systematic sampling the samples drawn are not overlapping.

In systematic sampling the population is listed and every k-th unit is taken after a random start between 1 and k. Each possible random start gives a different sample, and these k possible samples divide the population between them: every unit belongs to exactly one of them, so no two samples share a unit.

The method is random because the start is chosen at random, and it usually gives a well spread, representative sample unless the list has a periodic pattern matching k. So the other three options do not describe it.
