Which of the following is a key feature of probability sampling methods?
A. They rely on convenience or judgment for selection
B. They avoid the use of a sampling frame
C. Each element has a known, non-zero probability of being selected
D. They are only used in qualitative research
Answer (2)
The key feature of probability sampling methods is that each element has a known, non-zero probability of being selected. This allows for a representative sample and reduces bias compared to non-probability methods. It is vital in quantitative research for making accurate generalizations. ;
