Answer:Purposive sampling
Explanation:
A purposive sampling :
A selection of the participants is done by looking at their characteristics as the overall group or population and dependent on the purpose of the study.
When one needs to tackle a target question fast without the worrying factor of proportinality this is a good sampling method to be chosen.
It can be divided into heterogeneous purposive sample and homogeneous sample .
Heterogeneous tackles various issues which relate to a particular phenomenon. Many number of participants are questioned in order to receive a broader view of the issue in question.
Homogeneous
A homogeneous purposive sample deals with participants that have similar characteristics. The above purposive sample can be said to be a homogeneous one because the professor has an interest on the students who are all high achievers and that is their similar characteristic.
