This was a presentation that was carried out in our research method class by our group it will be useful for phd and master students quantitative and qualitat. The sample of a study is the group of subjects in the study sampling is the process whereby a researcher chooses his or her sample the five steps to sampling are: identify the population specify a sampling frame specify a sampling method determine the sample size implement the plan. This guide can help you choose which method to use simple random sampling is the ideal, but researchers seldom have the luxury of time or money to access the whole population, so many compromises often have to be made probability methods this is the best overall group of methods to use as you can subsequently use the most.
Sampling methods sampling and types of sampling methods commonly used in quantitative research are discussed in the following module learning objectives.
