5.Types of sampling techniques used in research include random sampling, stratified sampling, and cluster sampling.
6. The rationales for the survey method in doing research activity include the ability to gather data from a large number of people, the ability to gather standardized data, and the ability to analyze data easily.
7. The importance of sampling is that it allows researchers to gather data from a representative sample of the population, rather than from the entire population. This saves time and resources and also helps to reduce bias in the results.
