What are the different types of sampling techniques?

There are several types of sampling techniques, including random sampling, stratified sampling, cluster sampling, and systematic sampling. Would you like to know more about any specific type?

Can you explain random sampling?

Random sampling is a technique where each member of a population has an equal chance of being selected. This helps to eliminate bias and ensures that the sample is representative of the population.

What about stratified sampling?

Stratified sampling involves dividing the population into distinct subgroups, or strata, and then randomly sampling from each stratum. This ensures that specific characteristics are represented in the sample.

How does cluster sampling work?

In cluster sampling, the population is divided into clusters, usually geographically, and entire clusters are randomly selected. This method is often more practical and cost-effective.

Can you give me an example of systematic sampling?

Sure! In systematic sampling, you select every nth member from a list of the population. For example, if you have a list of 100 people and you want a sample of 10, you might select every 10th person.
