In which type of sampling does the subject not have an equal chance of selection?

• A) Probability sampling
• B) Non-probability sampling
• C) Stratified sampling
• D) Cluster sampling

Excellent! You’re correct. In non-probability sampling (B), the subject does not have an equal chance of selection.

Here’s why the other options aren’t the answer:

• Probability sampling (A): This type of sampling ensures every member of the population has a known and equal chance of being included.
• Stratified sampling (C): While it involves dividing the population into subgroups, each member within a subgroup still has an equal chance of being selected.
• Cluster sampling (D): Similar to stratified sampling, clusters are created, but within each cluster, individuals have an equal chance of being chosen
