Study Notes
Purpose of Sampling
- The primary purpose of sampling is to select a subset of individuals or data points from a larger population to make inferences about the entire population.
- Sampling allows researchers to collect and analyze data more efficiently and cost-effectively, while still maintaining a representative sample of the population.
Risks of Non-Random Sampling
- A potential risk of using a non-random sampling method is that the sample may not be representative of the entire population, leading to biased or inaccurate results.
- Non-random sampling methods, such as convenience sampling or snowball sampling, can lead to sampling bias and affect the validity of the study.
Considerations for Conducting Sampling
- An important consideration when conducting sampling is to ensure that the sample is representative of the population, and that the sampling method is appropriate for the research question and study design.
- Researchers should also consider the sample size, selection criteria, and potential sources of bias when conducting sampling.
