Research design has four major types which are discussed in detail below:
#1 Exploratory Research Design
This study strategy is utilized for studies that have never been done before and have no previous studies to refer to. The emphasis is on gaining knowledge and familiarity in preparation for further examination or when research challenges are in the beginning stages of the investigation. Exploratory designs are frequently used to determine how best to proceed with a study or what methodology would be most effective in collecting information about an issue.
This research will indicate whether or not a future study is feasible, and later strategies for more research can be devised. The results of the exploratory group are not applicable to the entire population; because of the unstructured nature of the research, the findings of this study are questionable. The design of exploratory research Issues is modified in order to conduct a more thorough analysis and formulate new hypotheses. Future studies and methodologies are being developed.
#2 Correlational Research Design
It’s suitable for both case-control and observational investigations. This is a non-experimental design that can be used by a researcher to determine the link between variables that have a close association. A correlation coefficient determines a relationship between the variables. A positive association is shown by a correlation coefficient of positive one (+1), whereas a negative relationship is indicated by a correlation coefficient of negative one (-1). The researcher develops a relationship between two connected variables in the study project using this research strategy. Furthermore, it is entirely quasi in character, and the variables are interdependent.
Ideally, a researcher should have two separate groups while adopting this strategy. When calculating the link between the variables, the researcher should avoid making any assumptions and instead use statistical analytic methods.
#3 Descriptive Research Design
Researchers employ this theory-based design to collect, evaluate, and present their obtained data. This research just addresses the question “what,” but it does not answer “how,” “when,” or “why.” Others will be able to appreciate the value of study because of this design.
However, a researcher can conduct a research study without a precise statement of the problem. Using the constraints of the study as a tool, a more targeted study can be produced. The descriptive design provides a broad picture of the investigation, which is valuable in determining which factors are worth investigating.
Analysis, data collecting, and presentation are common procedures used by researchers with this design. This method collects a vast amount of data for the research. With the help of this study, a wealth of data for future reference can be
#4 Experimental Research Design
This design is used by researchers to establish a link between a cause and an effect; basically to look into what causes things to happen. It can be employed in a lab setting or in a field setting. The experimental design is the procedure’s blueprint that allows researchers to regulate all aspects of the experiment. More groups and measurements are used in experimental designs for a longer length of time. It aids researchers in distinguishing between placebo and therapeutic effects.
This framework can also include a quasi-experiment research design. A researcher observes the influence of an independent variable on a dependent variable when utilizing this design. This type of study design typically aids in the resolution of a certain problem by modifying the independent variables. For a single study, it provides a high degree of evidence.
