Examination of Delphi and Quasi-experimental Research Designs

In most cases, scholars view research as large samples of subjects that are either participating in either two groups. Most research studies are considered as an experimental group whereby a treatment, independent variable (IV), or intervention is presented or a control group in which such interventions are not presented (Alberto & Troutman, 2016). Based on case study level C, Case 2, the independent variable is the treatment that is needed to change Rachel’s attitude in class. In the group designs, there is involvement of many subjects with each having an averaged performance, Dependent Variable which is comparable in the evaluation of experimental control. Therefore, Dependent variable in Rachel’s case is her behavior.

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as

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.

In this discussion post I will discuss locating psychology research and my result from Capella University Library Research and Information Literacy Skills also known as the RAILS.

3. A _(B) Small n design has many observations on a single case or a few subjects.

19. The text points out a common misconception about the term “controlled experiment”. In the

Under the research design section it could have been mentioned that the study was a descriptive correlation design, experimental design, Quasi-experimental design, or a comparative descriptive design which is "used to describe a phenomenon of interest and related variable" (Gray, Grove, & Sutherland,

I conducted a quasi-experimental research design comparing the data of students that completed the redesign course to students taking the original course. The results from this study indicated a decrease in the failure rates for student participating in the redesigned course by 5%. Another concern that influenced this study was the number of grade appeals received for this course. For this course, I would receive 40 to 50 grade appeals per year. For all other courses, I might receive one or two grade appeals per year. The research results found that students’ satisfaction with their instructor’s behavior and their overall opinion about the course increased after the course redesign was implemented. Now, I might receive one grade appeal a year for this course.

The site of Delphi is well known for its unique oracular Greek temple on Mount Parnassus and its continual importance is reflected through its changing historical context. From the political, social and historical importance placed on the Pythia by the ancient Greeks and Spartans to the emergence of the Sophists movements of Athens and onwards to the modern resurgence of interest in the fields of excavation and conservation in contemporary times, the site of Delphi has remained an historical site of significance for over a thousand years.

Quasi-experimental research, which was once considered ‘flawed’ and less superior to true experimental research, has become increasingly popular over the last three to four decades in many areas, especially the social sciences (Coolican, 2014, p. 121). It differs from true experimental research design in the way that quasi-experimental research doesn’t involve random assignment of participants to groups and often has less control over the independent variable (Follmer Greenhoot, 2003, p. 94; Coolican, 2014, p. 121). An

The research design is quasi-experimental using ex post facto designs. Ex post facto designs do not include random assignment; subjects are found who already fit into one of the experimental groups (Bachman & Schutt, 2014). Women were interviewed then assigned to four groups for analysis: Success, having exited prostitution at the time of the interview for at least six months; yo-yo, those who

Today’s managers have a growing need to understand scientific findings and incorporate them into decision making. Research always facilitates effective management. At many government organizations research drives every aspect of major decision making. In some organizations, research is so fundamental that management makes hardly any significant decision without the benefit of some kind of research.

A study design is the procedure that guides a researcher on how to collect, analyze and interpret observations. It is a logical model that guides the investigator while he navigates through the various stages of the research. Study types can be classified severally depending on the research strategy employed. A study type can be non-interventional that is ‘observational’ where a researcher just observes and analyses researchable objects or situations without intervening. Non-interventional study designs can be exploratory, descriptive or comparative. A study can also be

During the development of technology, most people have shifted to use electronic books to read both academic and non-academic texts. However, despite the technological changes, there has been a wide debate about the benefits of paper books over the e-books. It is important to understand that various reasons are suggesting why people should shift back to using the traditional books rather than the electronic ones. Even though some think that e-books are better that traditional ones, I believe that readers should return to traditional books because of various reasons.
