What is the objective of using survey case study and experiment in research?

The objective of using surveys, case studies, and experiments in research is to gather comprehensive data that can provide insights into specific phenomena or behaviors. Surveys allow researchers to collect quantitative data from a larger population, while case studies offer in-depth qualitative insights into particular instances or individuals. Experiments enable researchers to establish causal relationships by manipulating variables in controlled settings. Together, these methods enhance the validity and reliability of research findings, allowing for a more nuanced understanding of the research question.
