Research design is influenced by the objectives of the research study and is critical to the process. Qualitative methods are employed in exploratory research while survey methods are typically used in descriptive research. Experimental research is applied to explanatory research (Shi, 2013). The design links the research methodology and research methods to allow for logical and valid inferences to be made. Without a good research design, there can be serious errors and significant omissions in the research study (Shi, 2013).
Choosing the most appropriate method of research for the study to be conducted is also very important. There are several methods available, each with its strengths and weaknesses. Some methods may be more efficient at collecting larger sample sizes, while others may be expensive and inefficient, and others could be cheaper and faster, yet not detailed enough. Oftentimes a combination of methods is a better approach than using individual methods (Shi, 2013).
A significant challenge to conducting good research includes the availability of resources. Research methods are dependent on the available resources, including knowledge, money, time, support, and analytic skills (Shi, 2013). The types of methods used in research are dictated by the budget available for this process. Hence the best methods might not be employed because of the cost factor (Shi, 2013).
