What are some common sampling methods in statistics?
Common sampling methods include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
Can you explain simple random sampling?
Sure! Simple random sampling means every member of the population has an equal chance of being selected.
What about stratified sampling?
Stratified sampling involves dividing the population into subgroups and then randomly sampling from each subgroup.
How does cluster sampling differ from stratified sampling?
In cluster sampling, the population is divided into clusters, and entire clusters are randomly selected, unlike stratified sampling.
Which method is the most effective?
The effectiveness depends on the research goals and population characteristics. Each method has its advantages.
