The advantages of purposive sampling
The advantages of purposive sampling is limitless. You can eliminate candidates that is out of the equation from the survey, and include those that fit the bill. It is pretty accurate and has a solid systematical approach that would quickly lead to the main targets in no time at all. Finally, the costs incurred would be greatly reduced, less resources needed to find the specified targets.
There are many advantages of carrying out purposive sampling. The people who have been selected for the sampling have been selected with a particular purpose already in mind. Some of the advantages involved in this type of sampling include:
•Those people who are unsuitable for the sampling study or who do not fit the bill have already been eliminated, so only the most suitable candidates remain.
•As the most appropriate people for the study have been selected, this process becomes a lot less time consuming.
•With fewer time constraints and a more accurate subject, the costs for carrying out the sampling project are greatly reduced.
•The results of purposeful sampling are usually expected to be more accurate than those achieved with an alternative form of sampling.
•If you are looking for a very rare or much sought after group of people for a particular research study, using purposive sampling may usually be the only way you can track them down.
