I would like to know whether random sampling is used for experimental research. Actually, how experimental research can be conducted. If anyone direct me, I would appreciate your assistance.
If your experimental research is in the context of social science e.g. quantitative research on cause & effect analysis, then random sampling is required for your experimental and control groups in order to generalize your findings to the whole population. In order to conduct an experimental research, may be you want to take a look on my following 2 YouTubes (after you clicked on the RG link, you need to click on the YouTube link). Note: these 2 experimental research are at conceptual level for me to brain dump the ideas I conceived and not gone through empirically study yet. If you are interested perhaps we can work on this research together.
