Question: What sampling technique is used by a committee of 100 students to assess any reaction to the introduction of a Pastoral Care into the school time table?
A ) stratified B ) random C ) cluster D ) systematic
Steps to derive
1 To ensure a representative sample of students from all year levels, the committee uses the stratified sampling technique.
2 In this case the strata are the year levels. Within each strata the committee selects a sample. So, in a sample of 100 students, all year levels would be included. The students in the sample would be selected using simple random sampling or systematic sampling within each strata.
3 So, stratified sampling technique best suits here.
