Little to No Cost
Convenience sampling is inexpensive.
It can be conducted without any financial costs in some cases.
A survey can be sent online which requires no travel.
Bias
Bias can occur using this method due to the lack of randomization.
[I]n convenience sampling, a researcher chooses the sample based on their availability and convenience.
There are not many rules to follow, said Dr. Lin.
The survey results are thus biased and cannot be generalized to the rest of the population.
Randomization may take place in different ways.
