Question

A researcher is studying underachievement of gifted children in a qualitative study. She samples two children who are achieving beyond expectations and two children who are achieving well below expectations in her sample. What sampling technique did she use?

Group of answer choices:

Maximum-variation sampling

Extreme-case sampling

Homogeneous sample selection

Typical-case sampling

Answer 1

The maximum variation sampling is used mainly to identify the range of a parameter in question. But since here the purpose is not to find the range of achievements rather it is to find the underachievement of gifted children hence the sampling technique is not Maximum Variation Sampling.

In extreme case sampling, the focus is on unique participants with some unique characteristics.

The research particularly focuses on children who either have achieved beyond expectations or well below expectations.

Hence, the sampling technique she has used here is - Extreme case sampling.

In homogenous sampling, the participants are selected without any condition. The selected participants are homogeneously distributed in the population. This is not the case here so this option is incorrect.

The typical case sampling is concerned with the average characteristics of the participants so as to develop a typical profile of the participants. This also is not the kind of sampling technique used here.

So

Correct Option is - Extreme-case sampling.
