Probability Sampling Method

It means every member of the population has an equal chance of selection. For producing results that represent the whole population you have to use the probability sampling method.

• Simple random sampling

In this method, each sample possesses an equal likelihood of selection that is at least once in a while.

• Systematic Sampling

In this method, from the sampling frame, individuals are selected at a regular interval.

• Stratified Sampling

In stratified sampling, individuals are divided into different subgroups based on their similar

characteristics.

• Cluster Sampling

In this type of sampling method, the subgroups of the population are used as the sampling unit, instead of individuals.

Non-probability Sampling

In non-probability sampling, individuals are picked based on non-random criteria, and every individual will not get the chance of being selected.

• Convenience Sampling 

It is the most convenient way of sampling because individuals here are selected based on the willingness of selection and availability.

• Quota Sampling

Market researchers use quota sampling to conduct their research. 

• Judgement Sampling

It is also known as selective sampling, it depends on the judgement of the researcher when

and who to choose for the research.

• Snowball Sampling

It is commonly used in the branch of social science when researching to reach groups or individuals.
