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.
Pros and Cons of a non-probability sampling
The statement is true that a sampling distribution is a probability distribution for a statistic.
It is not!
With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
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.
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.
Non-probability sampling is a type of sampling technique whereby all the units of a population do not have an equal chance of being selected in the sample.it may further be divided intoConvenience: Sampling units are selected as per convenience of the researcherPurposive: The units selected in a sample are selected because they posses some requires characteristic e.g., clinical knowledge etc
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.
hihi
advantage of 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.
Non probability sampling is where the samples are not selected randomly.
Answer is Quota sampling. Its one of the method of non-probability sampling.
Pros and Cons of a non-probability sampling
Reduced or limited generalizability
Convenience sampling or quota sampling.
