In which of the following sampling methods. the sample is also known as an accidental sample and a haphazard sample? 

Key Points

• Convenience sampling is a non-probability sampling method in which the sample is selected based on convenience.
• This means that the researcher selects the sample based on who is available or who is easy to access.
• Convenience sampling is often used when it is not possible to use a more rigorous sampling method, such as random sampling. However, convenience sampling is not without its drawbacks.
• The sample may not be representative of the population, and the results of the study may not be generalizable.

Hence, the sampling method that is also known as an accidental sample and a haphazard sample is convenience sampling.

Additional Information Purposive sampling: 

• Purposive sampling is a non-probability sampling method in which the sample is selected based on the researcher's judgment.
• The researcher selects the sample based on who they believe will provide the most information about the research question.

Quota sampling:

•  Quota sampling is a non-probability sampling method in which the sample is selected to represent different subgroups of the population.
• The researcher sets quotas for each subgroup, and then selects participants until the quotas are met.

Stratified random sampling:

•  Stratified random sampling is a probability sampling method in which the population is divided into strata, and then a random sample is selected from each stratum.
• This ensures that the sample is representative of the population.
