SW650 Midterm Review Test Questions And Answers. Verified 100% Correct Quantitative Research Methods - ANSWER -uses large surveys, questionnaires, secondary research, looking at large samples. Reports data primarily in numerical form. Qualitative Research Methods - ANSWER -research in which the emphasis is placed on observing, describing, and interpreting people's behavior Protection of Human Subjects - ANSWER --risk and harm minimized and explained -informed consent provided -no coercion to participate -withdrawal allowed -privacy and confidentiality assured Institutional Review Board (IRB) - ANSWER -committee of administrators, scientists, and community members that reviews proposals for research involving human participants Research Ethics - ANSWER -the guidelines researchers follow to protect the rights of animals used in research and humans who participate in studies vulnerable populations - ANSWER -Persons with diminished autonomy; specifically children, people with cognitive impairments, older adults, people with severe health problems, employees, and students. informed consent - ANSWER -an ethical principle that research participants be told enough to enable them to choose whether they wish to participate Confidentiality - ANSWER -Respecting the privacy of both parties and keeping details secret anonymity - ANSWER -the condition of being anonymous study variables - ANSWER -concepts that are measured, manipulated, or controlled in a study Independent Variable (IV) - ANSWER -Variables that are either descriptive or those that the research can manipulate. They may influence, affect, or somehow be associated with the situation that you are studying. Independent variables generally precede the dependent variable in time. Dependent Variable (DV) - ANSWER -Variables that result from the independent variable, that the researcher is trying to explain, examine or predict. The variable that is being measured. Operational definition of a variable - ANSWER -description of how variables will be measured or manipulated in a study single subject design - ANSWER -a research design that requires only one or a few subjects in order to conduct an entire experiment AB design (SSD) - ANSWER -A Part is the baseline measurement collected prior to intervention. B Part is the data collected during the intervention. ABA Design (SSD) - ANSWER -Where the Second A phases is recorded during a period of no intervention(Post Intervention). ABAB Design (SSD) - ANSWER -Each phase of the AB Design is repeated twice. Group designs notation: x and O - ANSWER -O stands for Observation (Pretest and Posttest) X stands for the intervention. Experimental Group Design - ANSWER -Any of a number of designs which employ scientific methods to test a hypothesis and control experimental variables in a highly structured manner. Random Assignment of participants. quasi-experimental design - ANSWER -Research method similar to an experimental design except that it makes use of naturally occurring groups rather than randomly assigning subjects to groups. Pre-experimental designs - ANSWER -designs that do not control for extraneous factors by randomization Internal Validity - ANSWER -Whether the intervention was truly responsible for the observed differences in a variable or if the differences of the variable were influenced by extraneous variables and alternative explanations. External Validity - ANSWER -extent to which we can generalize findings to real world settings Threats to Internal Validity - ANSWER -History, Maturation, Instrumentation, Testing, Selection of Subjects, Regression to the Mean, Mortality History (threat to internal validity) - ANSWER -This refers to specific events (for example, national crises, tragedies, or on a local level, a large factory laying off hundreds of employees) that occur between the pretest and poshest that were not part of the researcher's design and that could influence the results. Maturation(threat to internal validity) - ANSWER -The aging of participants or different rates of physical growth or development within comparison groups are examples of influences that you should recognize and attempt to control as much as possible. The simple passage of time is an alternative explanation that should be discounted when gauging the effects of an intervention that runs over several weeks or months. The longer the intervention, the more likely that (client) maturation (the passage of time) play a role.
