What are some alternative sampling methods in statistics?
Alternative sampling methods include stratified sampling, cluster sampling, and systematic sampling. Would you like to know more about any specific method?
Can you explain stratified sampling?
Stratified sampling involves dividing a population into subgroups, or strata, and then taking a sample from each stratum. This ensures representation from all segments of the population.
What about cluster sampling?
Cluster sampling involves dividing the population into clusters, usually geographically, and then randomly selecting entire clusters to sample. It's often more practical and cost-effective.
How does systematic sampling work?
Systematic sampling selects every nth individual from a list or sequence. For example, if you have a list of 100 people and want a sample of 10, you might select every 10th person.
