Snowball sampling is often used when interviewing. Instead randomly asking people about a particular topic, you would interview initially a person thought to be knowledgable about a subject and then ask them to identify additional people who could serve as usefull interviewees. You then interview those people and ask them to suggest even more people. Thus, your pool of interviewees increases over time, something akin to making a big snowball where it slowly groes as you add more snow.
What else can I help you with?
What is the difference between quota sampling and cluster sampling?
What is the difference between quota sampling and cluster sampling
Is cluster sampling random?
It can be but it is not simple random sampling.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What does all the population in a certain area make up?
What I believe you are referring to is cluster sampling or cluster. In cluster sampling, the population is divided into clusters and all population members in the cluster are sampled.
How do multistage sampling applies to real life situation?
Multistage sampling is a form of cluster sampling where instead of using the entire cluster, random samples from each cluster are used. This is typically used when doing opinion polls or surveys.
Breifly explain three different examples of sampling?
simple random, stratified sampling, cluster sampling
Mention different types of sampling in statistics.?
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
Which sampling method is based on probability?
There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
What are advantages and disadvantages in cluster sample?
Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.
Which one is called non probability sampling a. cluster sampling b.quota sampling c. systematic sampling d. stratified sampling?
Answer is Quota sampling. Its one of the method of non-probability sampling.
What random samples does not require a sampling frame?
Random samples that do not require a sampling frame include convenience sampling and snowball sampling. In convenience sampling, researchers select individuals who are easily accessible, while snowball sampling relies on existing study subjects to recruit additional participants, often used in hard-to-reach populations. Both methods do not require a comprehensive list of the entire population, which is a key characteristic of traditional sampling frames.
When a research problem is related to heterogenous population the most suitable sampling method is?
cluster sampling
