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.

Instead of exploring or describing a phenomena, quantitative methods deal with facts and statistics. This type of research is often used in science or medicine.
Mixed methods combine qualitative and quantitative research. This type of methodology uses several different measures that include both contextual understanding like interviews or observations along with facts or statistics.
Using mixed methods can help the researcher investigate a topic on multiple levels, gaining different views and a comprehensive look at the subject. A mixed methodology meshes more than one philosophical perspective, allowing for the integration of different theories and ideas.
Within each major methodology are various designs. These provide a framework or philosophy for the study, and are different than the actual methods used. For example, a case study design focuses on exploring and describing a specific instance, person or group. A researcher may use observations, interviews or self-reports from the subject to create a complete picture. This picture, or case, provides a detailed example of a phenomenon that can then be generalized to a similar population.

Qualitative Research Qualitative research seeks to explore a specific phenomena, not prove a prediction, according to "Qualitative Research Methods: Quantitative Methods Quantitative research is is more objective than qualitative methods.
Types of research methods can be classified into several categories according to the nature and purpose of the study and other attributes. In methodology chapter of your dissertation, you are expected to specify and discuss the type of your research according to the following classifications.
Research can be classified in many different ways on the basis of the methodology of research, the knowledge it creates, the user group, the research problem it investigates etc.
Observational research methods, such as the case study, are probably the furthest removed from the established scientific method. This type is looked down upon, by many scientists, as ‘quasi-experimental’ research, although this is usually an unfair criticism. Observational research tends to use nominal or ordinal scales of measurement. Before beginning any research project, you must decide which methodology to use. This will guide your study, help you to choose a way to collect data and aid in your analysis. Researchers use three primary methodology types: qualitative, quantitative and mixed methods.
Types of Research Methods Adapted from Edvantia SBR Rating for Technical Assistance Programs and Services form () and Carter McNamara Overview of Methods to Collect Information handout. A research method is a systematic plan for conducting research. Sociologists draw on a variety of both qualitative and quantitative research methods, including experiments, survey research.
