Question

Match the following sampling methods to the correct type: A researcher samples 10 students from the accessible population of 25 students. All names are placed in a container, and the researcher draws 10 names from the container as potential participants.

a. Simple random sampling
b. Stratified random sampling
c. Convenience sampling
d. Cluster sampling

Answer 1

In the example described, the researcher uses simple random sampling, which gives each student an equal chance to be selected for the sample.

Step-by-step explanation:

In the scenario provided, where a researcher samples 10 students from the accessible population of 25 students by placing all names in a container and drawing 10 names, the sampling methods used is simple random sampling. This method gives every member of the population an equal chance of being included in the sample, and is considered one of the most accurate forms of random sampling when it's important that the sample accurately reflects the entire population.

Some other commonly used sampling methods include:

• Stratified random sampling: dividing the population into strata based on a particular characteristic, and then sampling from these strata proportionally.
• Cluster sampling: dividing the population into clusters randomly selected to be part of the sample, where every member of a selected cluster is included in the sample.
• Convenience sampling: selecting a sample that is convenient to study, which may not be representative of the entire population and could potentially lead to biased results.
