Advantages * Can be more accurate than hand-drawn designs - it reduces human error. 4 Key characteristics of Research Design a) Neutrality The results collected in research should be free from bias and neutral. How to create a research design? In tandem with the research questions and accompanying objectives, the study adopted the survey approach (personal interviews). Multi-method . It has been noted that "exploratory research is the initial research, which forms the basis of more conclusive research. Researchers must also have good interviewing skills, have the courage to ask follow-up questions, and be able to form professional bonds with participants to ensure the accuracy of the data. Describe two advantages of qualitative research design (One paragraph) 3. According to Thyer, the research design has the following components: Research Design A researcher begins the study by framing the problem statement of the research work. On the contrary, the benefit of employing techniques from both approaches in a single study is a recognized aspect, which resulted in a new style called multi-method research. With the help of this research, you can study the statistical relationship between the two variables. It can be concluded the multi-method research design is a useful method that can combine the strengths and the weaknesses of the quantitative and the qualitative elements of studies. 1 Quantitative research produces objective data that can be clearly communicated through statistics and numbers. Disadvantages * The software itself can be expensive so initial costs are high. It directs the experiment by orchestrating data collection, defines the statistical analysis of the resultant data, and guides the interpretation of the results. As the output is in emphasizes form, it is easy for the researcher to deduce results and implement them. 1 In that regard, the present paper will attempt to provide an overview of the advantages of conducting a study using a multi-method research design. Cross-Sectional Designs. A well-planned research design helps ensure that your methods match your research aims, that you collect high-quality data, and that you use the right kind of analysis to answer your questions, utilizing credible sources. * Control over extraneous variables is usually greater than in other research methods. Advantages of The Mixed Methods Approach . Academic voice is usually written in the third person (he, she, it), also not first person (I, we) or second person (you). Control over variables This kind of research looks into controlling independent variables so that extraneous and unwanted variables are removed. It gives researchers a high level of control. Discuss and get evaluated your conclusion with experienced multiple individuals and consider those who agree with your research's results. Researchers use quantitative methods to observe situations or events that affect people.
