List I

i.Simple Random Sampling

ii.Stratified Random Sampling

iii.Cluster Sampling

iv.Snowball Sampling

List II

a.The first member is used as an informant to identify others; the process goes on like this

b.The units are chosen intact on the basis of their settings

c.The units are chosen from defined groups/levels randomly

d.The units are chosen by giving an equal and independent chance to each

Ai-a, ii-b, iii-c, iv-d

Bi-d, ii-c, iii-b, iv-a ✓ Correct

Ci-c, ii-d, iii-a, iv-b

Di-b, ii-a, iii-d, iv-c

Correct answer: (B) i-d, ii-c, iii-b, iv-a

Explanation

Simple random sampling gives each unit an equal independent chance, stratified samples from defined levels, cluster chooses intact settings, and snowball uses one member to find others.

Simple random sampling pairs with giving each unit an equal and independent chance of selection.

Stratified random sampling pairs with choosing units randomly from defined groups or levels.

Cluster sampling pairs with choosing units intact on the basis of their settings.

Snowball sampling pairs with using the first member as an informant to identify others in turn.

Snowball sampling is a non-probability technique suited to hidden or hard-to-reach populations.
