Carlene Reyes 809000173 Question 2: Describe the relationship between research design and sample design Before examining both sample design and research design it is important to be clear about the role and purposes of each design. Research design is a plan for collecting and utilizing data so that desired information can be obtained with sufficient precision or so that a hypothesis can be tested properly. Every type of empirical research has a form of implicit research design. A design is a logical sequence that connects to empirical data to a study’s initial research question and ultimately it, to its conclusion. According to Adam G Bluman in his book Elementary Statistic define research design as a logical plan from getting from here to there, where here may be defined as initial questions to be answered , and there is some conclusion (answers) to these questions . Another text book has described research design as a plan that guides the investigator in the process of collecting analyzing and interpreting observations. It is a logical method of proof that allows the researcher to draw inreferences concerning causal relations among the variables under investigations (Nachmias andNachmaias 1992 pp. 77-78). Research design can be seen as the “blue print” for your research, dealing with at least four problems what question to study, what data are relevant, what data to collect and how to analyze the results. As a result research design is more than just a work plan it is what makes social science scientific. In addition there are various forms of research design that can be broken up into both quantitative and qualitative research design. Qualitative research follows a naturalistic paradigm which is based on the idea that reality is not predetermined, but is constructed by the participants in the research (Vishnevsky and...
