Non-experimental research design refers to a type of research methodology that does not involve manipulating variables or assigning subjects to experimental or control groups. Instead, non-experimental research relies on observing and analyzing existing data or natural settings to answer research questions.
Non-experimental research designs are often used in fields such as sociology, psychology, and education, where it may be ethically or practically difficult to manipulate variables or assign subjects to different groups. This type of research design is also useful for studying phenomena that occur naturally, such as social relationships, cultural practices, and environmental factors.
There are several types of non-experimental research designs, including:
Descriptive research: This type of research involves collecting and analyzing data to describe the characteristics of a particular group or phenomenon.
Correlational research: This type of research investigates the relationship between two or more variables, without manipulating any of them.
Survey research: This type of research involves collecting data from a sample of individuals through self-report measures, such as questionnaires or interviews.
Case study research: This type of research involves in-depth analysis of a single case or small number of cases, often using a variety of data sources.
One of the main advantages of non-experimental research is that it allows researchers to study real-world phenomena in their natural setting, providing a more accurate representation of the phenomenon being studied. However, non-experimental research also has some limitations, as it is difficult to establish causality or control for extraneous variables.
Overall, non-experimental research design is a useful approach for studying a wide range of phenomena and can provide valuable insights into the relationships and patterns observed in the real world.

. Experimental designs control for most threats to internal validity. Descriptive Research Designs Descriptive research designs are applied in various qualitative studies which use observation and interview methods such as case studies, ethnography among others. In this article, we will not only discuss the key aspects of experimental research designs but also the issues to avoid and problems to resolve while designing your research study. A Comparative Study on the Motivations for Online Identity Reconstruction Between China and Malaysia. Differences were found not only between Chinese and Malaysian participants but also among participants from different ethnic groups e. Recall the three goals of science are to describe, to predict, and to explain.

The simplest example of an experimental research is conducting a laboratory test. Each row is read from left to right. Experimental research tends to be highest in internal validity because the use of manipulation of the independent variable and control of extraneous variables help to rule out alternative explanations for the observed relationships.
Qualitative inquiry and research design: Choosing among five traditions. Different interventions will be given to the groups. Experimental research is the type of research that uses a scientific approach towards manipulating one or more control variables and measuring their defect on the dependent variables, while non-experimental research is the type of research that does not involve the manipulation of control variables. Recall the three goals of science are to describe, to predict, and to explain. It is also called experimental research.
This allows the researcher to identify cause-and-effect relationships, which is a great advantage to experimental designs. Usually, the experimenter assigns two or more groups with similar characteristics. This study adds knowledge to the research concerning online identity reconstruction by taking into account national culture. What is non experimental research in quantitative research? He was primarily interested in the extent to which participants obeyed the researcher when he told them to shock the confederate and he observed all participants performing the same task under the same conditions. Correlational research is very similar to cross-sectional research, and sometimes these terms are used interchangeably. But if it was a cross-sectional study, it could only be concluded that these variables are statistically related.
Experimental Research Designs: Types, Examples & Advantages
The experiment is conducted in the natural environment of the participants. Again, the choice between the experimental and non-experimental approaches is generally dictated by the nature of the research question. This is because although experimental research can provide strong evidence that changes in an independent variable cause differences in a dependent variable, non-experimental research generally cannot. Upper Saddle River, NJ: Merrill Prentice Hall, Thousand Oaks. In quasi experimentation the independent variable is selected rather than varied or manipulated by the experimenter. Therefore, incorrect statistical analysis could affect the quality of any quantitative research. The SAGE encyclopedia of educational research, measurement, and evaluation Vols.
If the researcher simply asked participants whether they made daily to-do lists or not, then the independent variable it is experimenter-selected and the study is cross-sectional. One of the major limitations of case study research design is that the results can not be generalized. As we will see, however, this inability to make causal conclusions does not mean that non-experimental research is less important than experimental research. If the goal is to describe or to predict, a non-experimental approach is appropriate. Anyone can implement it for research purposes. Open Access Correlational Studies Adams, R.
Using econometric ordinary least squares and probit models, we explore the factors that drive poverty reduction. For example, do you want to see if a particular intervention relieves feelings of anxiety? For instance, academic performance of students is positively related to their self-esteem. The Review of Economics and Statistics, 84 1 , 151-161. A quasi-experimental design is similar to a true experimental design. Research Limitations Every study has some 6.
As such, evidence that supports the cause-and-effect relationships is largely limited. Correlational research is considered non-experimental because it focuses on the statistical relationship between two variables but does not include the manipulation of an independent variable. For example, thematic analysis would focus on themes that emerge in the data or conversation analysis would focus on the way the words were said in an interview or focus group. Nonexperimental designs include research designs in which an experimenter simply either describes a group or examines relationships between preexisting groups. Experiments are generally high in internal validity, quasi-experiments lower, and correlation non-experimental studies lower still.
