Quasi-Experimental Designs Milagros V. Mercado Walden University PSYC-3003-12 Methods in Psychological Inquiry Instructor: Meredith McKee 09/28/2011 Quasi-Experimental Designs According to (Stangor, 2011. pp. 274), quasi-experimental design is employed when there are two groups of people that cannot be assigned randomly to other groups. Also, in this type of design the variables cannot be manipulated as they would be in other types of experiments and the variables are measured rather than manipulated, (pp.274). In this case, there are four different studies that are important to assess as to their variables and how they would work. The first study that I chose is study one that demonstrates that women perform more poorly, on†¦show more content†¦In addition, the intended outcome would be that women would perform higher on the mathematics section after they had the tutoring. Boyd (2002), states that this would not be a true comparison group because the research participants are being compared against themselves. However, this would be in addition to the first experiment. Furthermore, the second study I chose study two because it demonstrates that lower-socioeconomic-status students benefit more over time from an academic tutoring program than do higher socioeconomic-status students. I would think this would also be true and would like to know more information on this one. The independent variable is the socioeconomic status of the students. The dependent variable is the tutoring program and its effect on performance. Another alternative research design that could be used to gain more information in this study would be a case study design. In this study, an individual could be chosen to research that was in this particular study. The purpose of the case study would be to understand the environment in which the individual grew up and how it has affected their ability to learn. The case study may provide insight into how lower-socioeconomic-status hinders the individual and perhaps why the academic tutoring program is successful.Show MoreRelatedEssay on Experimental and Quasi-Experimental Designs679 Words   |  3 PagesExperimental designs Experimental designs are viewed as the most accurate, and most demanding of research designs, requiring strict attention to rules and procedures. Researchers use these research designs to manipulate and control testing procedures as a way to understand a cause and effect relationship. Commonly, independent variables are manipulated to judge or decide their effect on a dependent variable (Trochim Donnelly, 2008). In order for an experiment to be considered aRead MoreDifference Between True Experimental Design And Quasi Experimental Research Design1064 Words   |  5 Pages Explain the difference between true experimental design and quasi-experimental research design. Provide examples. Quasi-experimental research designs and experimental research designs both have one aim, which is to test a casual hypothesis (UNICEF, 2014). A true experiment can be defined as testing a hypothesis with randomly assigned groups, where as a quasi experiment can not, so it is simply an experiment that isn’t a true experiment (Kowalczyk, 2015) The main difference stems from the randomisationRead MoreExperimental And Quasi Experimental Research Design1582 Words   |  7 Pages Research Configuration: Research design can be categorized into two sections including experimental and quasi-experimental research design ((Soy, 2015). In an experimental research design, the researcher needs to assign the subjects based on random selection. The subjects are assigned to particular groups for a different level of treatment. On the other hand, the quasi-experiment design suggests a process where the researcher avoids randomization, as the subjects are not selected randomly. TheRead MoreCorrative Research Design And Quasi-Experimental Design1316 Words   |  6 Pages The strategy behind this design is that with the quasi- experimental design and the use of a longitudinal design there would be a better collection of data because it would provide an idea of when bad parenting affects the child and the child starts acting in a delinquent manner, and also it would show if the delinquency follows to their early/ late teen years in high school. For the purpose of this study, the group of individuals being studied would be the children that have turned delinquentRead MoreExamination of Delphi and Quasi-experimental Research Designs1708 Words   |  7 Pagessolutions for known problems. The Delphi and quasi-experimental studies provide examples of research performed in library science. The Delphi Study The Delphi study was developed by The RAND Corporation in the 1950s for the Air Force and was primarily used to forecast future events based on expert opinions (Wildemuth, 2009). Delphi studies provide an alternative to the traditional round-table type discussion (Cypher Gant, 1971). The Delphi design depends on three components: anonymity, controlledRead MoreDifference Between True Experimental And Quasi Experimental Research Design1070 Words   |  5 Pagesbetween true experimental and quasi-experimental research design. Provide examples in your answer. (265 words) True experimental and quasi-experimental research designs are the two most common forms of research design. While they both share similar elements, such as measuring participant results to test the hypothesis, there are also significant differences between true experimental and quasi-experimental research designs (The Regents of the University of Michigan, 2013 ). True experimental researchRead MoreDifference Between True Experimental And Quasi Experimental Research Design Essay1169 Words   |  5 PagesPSY201 ~ Assignment 2: Short Answer Quiz Question 1 Explain the difference between true experimental and quasi-experimental research design.

They share some common characteristics such as measuring collected data to test the hypothesis, although, overall there are many differences between the two, especially in regards to the type of researchRead MoreDesign: A Quasi Experimental Design (Study/Control) Was1406 Words   |  6 PagesDesign: A quasi experimental design (study/control) was utilized to examine the effect of using risk reduction intervention to reduce risk of osteoporosis and osteoporotic fracture. Setting: The study was conducted at the outpatient clinics in Menoufia University Hospital, at Shebin El-Kom City, Menuofia Governorate. The University Hospitals was selected because of the considerable number of people at high-risk for osteoporosis attending to these outpatient clinics (1500) patients every month.

This data is collected from the Center of Children and Family Services in Hampton, Virginia using the Domestic Violence Inventory (DVI). The offenders will complete a DVI pretest, receive the group intervention, and then complete a DVIRead MoreQuasi-Experimental Group Design To Compare Recidivism Rates Of Opioid Offenders?892 Words   |  4 PagesMethods Research Design The current study will utilize a quasi-experimental group design to compare recidivism rates of opioid offenders in drug courts compared to offenders on probation. Since, random assignment to control and experimental groups are not feasible, the two groups will be matched on various demographic characteristics as well as the current choice of drug. The data will be collected on all participants that have entered the Brooklyn Treatment Court, NY (BTC) in the second judicial
