Convenience sampling is a type of nonprobability sampling in which people are sampled simply because they are “convenient” sources of data for researchers. In probability sampling, each element in the population has a known nonzero chance of being selected through the use of a random selection procedure.
Is convenience sampling random sampling?
Convenience sampling is a type of non-probability sampling , which doesn’t include random selection of participants. The opposite is probability sampling, where participants are randomly selected, and each has an equal chance of being chosen.
Is convenience sampling a type of purposive sampling?
The terms purposive sampling and convenience sampling are often used interchangeably, but they do not mean the same thing. Convenience sampling is when researchers leverage individuals that can be identified and approached with as little effort as possible .
Is convenience sampling qualitative or quantitative?
Yes, convenience sampling is allowed in quantitative research . What is crucial is, since convenience sampling is prone to the challenge of representativeness, the researcher must ensure the sample is relatively a reflection of the population of the study.
What types of bias is convenience sampling?
Since the sampling frame is not know, and the sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalisations from your sample to the population you are studying.
How do you explain convenience sampling?
Convenience sampling is a type of nonprobability sampling in which people are sampled simply because they are “convenient” sources of data for researchers . In probability sampling, each element in the population has a known nonzero chance of being selected through the use of a random selection procedure.
How do you use convenience sampling?
In its basic form, convenience sampling method can be applied by stopping random people on the street and asking questionnaire questions . ‘Pepsi Challenge’ marketing campaign can be referred to as a relevant example for this sampling method.
Can you use both convenience and purposive sampling?
The study also shows that although, convenience sampling can be used in both qualitative and quantitative study , but it is frequently used in quantitative study while purposive sampling is typically used in qualitative study.
Where is convenience sampling used?
A basic example of a convenience sampling method is when companies distribute their promotional pamphlets and ask questions at a mall or on a crowded street with randomly selected participants . Businesses use this sampling method to gather information to address critical issues arising from the market.
What is purposive sampling example?

What are the types of qualitative sampling?
In this section, we briefly describe three of the most common sampling methods used in qualitative research: purposive sampling, quota sampling, and snowball sampling . As data collectors, you will not be responsible for selecting the sampling method.
What are the advantages of convenience sampling?
One of the most common examples of convenience sampling within developmental science is the use of student volunteers as study participants. The key advantages of convenience sampling are that it is cheap, efficient, and simple to implement.
Is snowball sampling qualitative or quantitative?
Snowball sampling is a commonly employed sampling method in qualitative research , used in medical science and in various social sciences, including sociology, political science, anthropology and human geography [1–3].
Is convenience sampling good?
Researchers use convenience sampling not just because it is easy to use , but because it also has other research advantages. In pilot studies, convenience sample is usually used because it allows the researcher to obtain basic data and trends regarding his study without the complications of using a randomized sample.
What is the best sampling method?
Simple random sampling : One of the best probability sampling techniques that helps in saving time and resources, is the Simple Random Sampling method. It is a reliable method of obtaining information where every single member of a population is chosen randomly, merely by chance.
What are the pros and cons of convenience sampling?
