Difference Between True Experimental And Quasi Experimental Research Design

A research design can be understood as the planning of any scientific research from the first to the last step. In this sense it is a program to guide the researcher in collecting, analyzing, and interpreting facts (Bless and Higson-Smith, 1995:63).

Instructions: This is a group activity that you will start in class and complete at home. For each of the following, note, whether the research design used is an experiment, a quasi-experiment, or a correlational approach and why. If a study is an experiment, identify the independent variable and the dependent variable. Please type your answers in complete sentences.

Research is the systematic investigation of the study of materials in order to establish facts, and help get to new conclusions. There are four types of research used to help with answering many questions in science. The four types are causal comparative, descriptive, experimental, and correlational researches. Causal comparative researches look for the cause of some type of effect. Descriptive researches look for a common characteristic within a similar population and determine how various characteristics affect behavior or achievement. Experimental research seeks for the effect of certain factors, also to find the independent variable and dependent variable of the experiment. Correlational research seeks for the relationships between variables in an effort to determine relationship between them.

There are some essential components of conducting research. Psychologists design their research experiments by using:

The research design used to complete the research will be a quasi-experimental research design. Quasi-experimental research is research that …………………….. A quasi-experimental approach is best for this research question because…………………..

Research designs are procedures used for collecting, analyzing, interpreting, and reporting data in research studies. There are many different models with separate procedures for each of them. Research designs help guide which methods a researcher will use during their studies. When a researcher identifies an issue used for research mixed methods they choose a specific research design that best fits the problem and research questions in the study. The four basic mixed methods designs are the convergent parallel design, the explanatory sequential design, the exploratory sequential design, and the embedded design (Creswell & Plano Clark, 2006).

Definitely the information I learned from the qualitative approach is deeper than the experimental and quasi-experimental designs. Understanding the purpose of the research and Unaware of the directions that will be presented totally makes a huge difference with the findings. With the qualitative research, the problem is known and it is being identified. But with quasi and experimental designs, it seems like a hit and miss

Principally, quasi-experiments utilize the comparison of two existing set of groups to determine the maximum level of impact caused by an intervention. The design is standard among behavioral researcher in determining the effects of an intervention before and after treatment. The design attempts to eliminate all other unrelated explanations to an outcome

research is observational in nature and a type of correlational research, and is often contrasted with

Define this type of research design and justify your answer with reference to the actual experiment.

My research design is Pre-Experimental Qualitative and is also Prospective study. A pre-experimental design uses observation of a single group to cause change and qualitative design provides insight on an issue and validates comparisons. My design uses a group of women who are taught the benefits of immediate skin to

Experiment- Experiment has three different methods. The first method is controlled experiments. In controlled experiments, researchers have a dependent variable that lets them

a. The study was designed as an experimental research by using independent and dependent variables.

There are also some differences between these study designs, which may cause some problems for the inexperienced researcher. “Quantitative research is objective; qualitative research is subjective. Quantitative research seeks explanatory laws; qualitative research aims at

Quantitative research design is the standard experimental method of most scientific disciplines. These experiments are sometimes referred to as true science, and use traditional mathematical and statistical means to measure results conclusively. They are most commonly used by physical scientists, although social sciences, education and economics have been known to use this type of research. It is the opposite of qualitative research. Quantitative experiments all use a standard format, with a few minor inter-disciplinary differences, of generating a hypothesis to be proved or disproved. This hypothesis must be provable by mathematical and statistical means, and is the basis around which the whole experiment is designed. Randomization of any study groups is essential, and a control group should be included, wherever possible. A sound quantitative design should only manipulate one variable at a time, or statistical analysis becomes cumbersome and open to question. Ideally, the research should be constructed in a manner that allows others to repeat the experiment and obtain similar results.
