Observational research is a group of different research methods where researchers try to observe a phenomenon without interfering too much. Observational research methods, such as the case study , are probably the furthest removed from the established scientific method. Observational research tends to use nominal or ordinal scales of measurement.
Observational research often has no clearly defined research problem , and questions may arise during the course of the study.
Observation is heavily used in social sciences, behavioral studies and anthropology, as a way of studying a group without affecting their behavior.
Whilst the experiment cannot be replicated or falsified , it still offers unique insights, and will advance human knowledge. Case studies are often used as a pre-cursor to more rigorous methods, and avoid the problem of the experiment environment affecting the behavior of an organism.
Observational research methods are useful when ethics are a problem. In an ideal world, experimental research methods would be used for every type of research, fulfilling all of the requirements of falsifiability and generalization. However, ethics , time and budget are major factors, so any experimental design must make compromises. As long as a researcher recognizes and evaluates flaws in the design when choosing from different research methods, any of the scientific research methods are valid contributors to scientific knowledge.

Qualitative methods are chosen when the goal of the research problem is to examine, understand and describe a phenomenon. These methods are a common choice in social science research problems and are often used to study ideas, beliefs, human behaviors and other research questions that do not involve studying the relationship between variables.
The following table lists and describes the most common research designs used at Grand Canyon University. Different research books will use different terms for similar types of research. However, the research designs identified in this document are fairly common in terms of their use and their terminology. Explore the relationship between two or more variables through a correlational analysis.
The intent is to determine if and to what degree the variables are related. It does not imply one causes the other. Intent is to study and understand a single situation, which could be a leader, a classroom, a process, program, activity.
Collect a variety of material in a specific and bounded time period. This is also used for historical studies, when collecting historical data to understand and learn from the past. Compare two groups with the intent of understanding the reasons or causes for the two groups being different. Test an idea, treatment, program to see if it makes a difference.
There is a control group and a test group. Individuals are randomly assigned to the two groups. One group gets the treatment test group and the other group control group does not get the treatment.
There is a pre and post-test for both groups in a traditional experimental design. It is the same as experiment in that there is a control and test group. However, current groups are used as is rather than randomly assigning people to the two groups. Both groups receive the pre and post- test in a traditional design. Studies a human experience at an experiential level such as understanding what it means for a woman to lose a child.
It is about understanding the essence or meaning of the experience. A mixed research design involves having both a quantitative design and qualitative design. Mixed designs is the best approach if the study requires both quantitative and qualitative designs to address the problem statement. Mixed design studies take significantly more time, more resources, and require the researcher to develop expertise in qualitative analysis techniques and quantitative analysis techniques.
Qualitative studies can use numbers, counts and even descriptive statistics. Using numbers does not mean the study has to be quantitative or mixed methods.

Action Research Design Definition and Purpose The essentials of action research design follow a characteristic cycle whereby initially an exploratory stance is This type of research is used to measure what impact a specific change will have on existing norms and assumptions. Most social scientists seek causal explanations that reflect tests.
THE CONTEXT OF DESIGN Before examining types of research designs it is important to be clear about the role and purpose of research design. We need to understand what research design is and what it is not. We need to know where design ﬁts into the whole research process from framing a .
research involves philosophical assumptions as well as distinct methods or procedures. Research design, which I refer to as the plan or proposal to conduct research, involves the intersection of philosophy, strategies of inquiry, and specific methods. A framework that I use to explain the inter-action of these three components is seen in Figure The research design for this study is a descriptive and interpretive case study that is data collection methods used in the study was discussed.
