It discusses the relationship between research design and statistical analysis, differentiating between exploratory and hypothesis testing research, as well as experimental and correlational research. A research design can be defined as the preparation of conditions, for the collection and analysis of data in such a manner, which aims at combining relevance to the research purpose with economy in procedure. One of the most common statistical tests is to see whether there is a link between two variables—that is, if you change one variable, will the other also change?. This paper investigates what research design is, the different kinds of research design and how a researcher can choose the appropriate research design for his her study.
