difference between probablity sampling and non probablity sampling
Answers
Answer:
Generally, nonprobability sampling is a bit rough, with a biased and subjective process. This sampling is used to generate a hypothesis. Conversely, probability sampling is more precise, objective and unbiased, which makes it a good fit for testing a hypothesis

Probability Sampling
In the technique of probability sampling, also known as random sampling, everyone in the population has an equal chance of being chosen as a representative sample:
Everyone in the sample must have the same probability, or fixed opportunity, to be in the sample set.
and
The probability of any member of the sample group being selected for the sample can be mathematically calculated. In other words, everyone has the same, a fair chance of being selected.
The characteristics of probability sampling can be summarized as follows:
Random basis of selection
Fixed, known opportunity of selection
Used for conclusive research
Produces an unbiased result
The method is objective
Can make statistical inferences
The hypothesis is tested
Nonprobability Sampling
One of the most noteworthy features of the method of nonprobability sampling, also known as nonrandom sampling, is that there isn't any specific probability that any given person will be in the sample set. In other words, you don't know which person from a population will be chosen for the sample.
Some characteristics of nonprobability sampling include:
Arbitrary basis of selection
Used for exploratory research
Produces a biased result
Uses a subjective method
Can make analytical inferences
The hypothesis is generated
