Pros and cons of cluster random sampling
Webb1 juni 2024 · Advantages of systematic sampling - It is easy to implement. - Works where there is no sampling frame as long as the items are physically in evidence. - Saves time and is not costly. Disadvantages of systematic sampling - Bias may occur where recurring sets in a population are possible. - This sampling technique is not perfectly random. WebbBiased Samples: This sampling is very biased as clusters are randomly selected from the entire population. It has also formed a biased opinion regarding research. High Sampling Error : The samples are generally error-based compared to another simple sampling method. Conclusion
