In some situations stratified random sampling may be more appropriate. You may have a population which can be divided up into a number of subsets (strata) such that the difference between units in different strata is much greater than the difference between units within each stratum. A probability sample may not have enough units from some of the smaller strata. A stratified random sample will ensure that each stratum is represented proportionally.
In other situations, cluster sampling may be more appropriate. Suppose you wish to visit a sample 1% of all schools in the country. If you were to choose the schools by probability sampling they would be all over the country and you would require a huge amount of time and money to visit them all. What you could do, instead, is to divide up the country into 1000 regions. Select 10 of these regions (1%) and then visit every school in the selected regions. Far less running around!

Differences between probability samplingand non-probability sampling?
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
Pros and Cons of non-probability sampling?
Pros and Cons of a non-probability sampling
What is sampling examine well known methods of probability and nonprobability sampling in statistic?
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
What are the two types of sampling?
The two main types of sampling are probability sampling and non-probability sampling. Probability sampling involves selecting samples in a way that each member of the population has a known chance of being chosen, ensuring that the sample is representative. Non-probability sampling, on the other hand, does not provide all individuals in the population with a known or equal chance of selection, which can lead to biases in the sample. Common methods include random sampling for probability sampling and convenience or purposive sampling for non-probability sampling.
What difference between Statistical Sampling and non statistical sampling?
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
What is non-probability sampling?
Non probability sampling is where the samples are not selected randomly.

What is sampling in research?
Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.
What is probability sampling and non probability sampling?
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.
What is sampling examine well known methods of probability and nonprobability sampling in statistic?
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
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 are the two types of sampling?
The two main types of sampling are probability sampling and non-probability sampling. Probability sampling involves selecting samples in a way that each member of the population has a known chance of being chosen, ensuring that the sample is representative. Non-probability sampling, on the other hand, does not provide all individuals in the population with a known or equal chance of selection, which can lead to biases in the sample. Common methods include random sampling for probability sampling and convenience or purposive sampling for non-probability sampling.
What is the major drawback of non-probability sampling compared to probability sampling?
Reduced or limited generalizability
Non -probability sample techniques?
Convenience sampling or quota sampling.
What are the differences between probability sampling and non probability sampling?
In a probability sample, each unit has the same probability of being included in the sample. Equivalently, given a sample size, each sample of that size from the population has the same probability of being selected. This is not true for non-probability sampling.
