Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.

What are the advantage and disadvantage of sampling techniques?

Sampling techniques in research allow researchers to gather data efficiently and cost-effectively, providing a snapshot of a larger population. This can save time and resources compared to collecting data from an entire population. However, sampling techniques may introduce sampling bias, where certain groups are overrepresented or underrepresented in the sample, leading to results that may not accurately reflect the entire population. It is crucial for researchers to carefully select and implement sampling techniques to minimize bias and ensure the validity and generalizability of their findings.


What are the advantages and disadvantages of systematic sampling in statistics?

Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
