Match an item in List-I with an item in List-II. Use the codes given below :

List - IList - II
(a) Systematic sampling(i) An item in the study population
(b) Sampling unit(ii) Probability sampling
(c) Snow-ball sampling(iii) Non-probability sampling
(d) Sampling frame(iv) List of units of analysis

Codes :
(a) (b) (c) (d)

  • A.(iii) (ii) (iv) (i)
  • B.(ii) (i) (iii) (iv)
  • C.(iv) (i) (ii) (iii)
  • D.(iv) (ii) (iii) (i)

Answer: B

Systematic sampling is a form of probability sampling (ii). A sampling unit is an item in the study population (i). Snowball sampling is a non-probability sampling method (iii), and a sampling frame is a list of the units of analysis (iv). So the code is (ii), (i), (iii), (iv), option B.

The other options take systematic sampling as non-probability or the frame as a population item, which is wrong.
