Which of the experimental examples below illustrates a study that would use an Ex Post Facto design?a researcher interested in studying the effects of students consuming energy drinks before taking an exama researcher who wants to study how obesity influences self-esteem levels in childrena researcher who wants to study how eye contact influences perceptions of trustworthiness in sales professionalsa researcher interested is studying how the presence of sunlight affects mood2. An Ex Post Facto design is considered to be quasi-experimental. Why?the dependent variable is the same for all groups in the experimentparticipants are randomly assigned in this kind of experimentthe experiment is being used to study health psychologyparticipants are not randomly assigned in this kind of experiment3. A researcher wishes to study how fatigue influences reaction time. To choose subjects for the group that is fatigued while performing tests to measure reaction time, the subjects names are put in a hat and blindly drawn out and placed in that group. The other participants will perform the tests while not fatigued. This is an example of _____.controlling a variable present prior to the studya true experiment randomly assigning participants to experimental and control groupscontrolling variables that could influence one anotheran experiment with an ex post facto design4. Why would a researcher employ the use of an Ex Post Facto Design in an experiment?they want each participant to have an equal chance of being in the experimental groupthey do not have access to a control groupthey want to study something you can’t ethically or physically controlthey plan to study only one variable5. An Ex Post Facto design is most often used with, but not limited to, which of the following types of experiments?developmental psychologyclinical psychologybehavioral psychologyhealth psychology Worksheet: Pretest-Posttest Design: Definition & Examplehttps://study.com/academy/lesson/pretest-posttest-design-definition-example.html1. When do researchers generally notice the practice effect?Only occurs when you use the exact same tests with each subject multiple timesParticipants answers change due to familiarity with questions or tasksParticipants are able to complete tasks faster due to prior experience doing the task in real lifeParticipants score 100% on tests with some coaching from the study designer2. In addition to enabling researchers to look at the total effect of the manipulation, pretest-posttest design is also good for measuring:The individual preference for tasksHow to better design questions and tasksThe specific effect on the individualA focus on group processes3. Why is pretest-posttest design referred to as quasi-experimental?Study participants are assigned to control groupThe effects on participants are not monitored carefullyStudy participants are asked to provide feedback on the study designStudy participants were not randomly assigned4. You performed a study and found no depression before the experimental manipulation but almost all participants had depression afterwards. What conclusion would you likely reach about the study?Your manipulation was likely the cause of the depressionThe practice effect of the manipulation led to strong depressive tendenciesMost of your subjects were already borderline depressedWorking with you causes depression in most people5. Example 1 discussed an experiment that required subjects to go without showering or cleaning up in any way for 36 hours. If the researcher truly wanted to discover whether being dirty impacted a subject’s judgment or knowledge, what about the design would need to be altered?The researcher would need to set up a control group and a randomly assigned group who did not shower for 36 hours.The researcher would need to run the study again with only subjects who had showered in the past 36 hour.The researcher would need to set up a control group who did not shower for 36 hours and a randomly assigned group of clean subjects.The researcher would need to investigate another group of dirty subjects but assign them different tasks. Worksheet: Types of Research Designs in Psychologyhttps://study.com/academy/lesson/types-of-research-designs.html1. Researchers conduct a study to determine whether natural lighting causes increased test performance as opposed to fluorescent lighting. What type of research will they conduct?Case studyDescriptive researchCorrelational researchExperimental research2. If a study about the relationship between intelligence and income produced a Pearson correlation coefficient of .90, it would suggest that:intelligence and income are not linkedas intelligence increases, income increasesas intelligence increases, income decreasesthe correlation between intelligence and income is insignificant3. The ‘stereotype threat’ refers to the hypothesis that women and racial minorities will:feel anxiety because of the stereotype that says they will perform badly on tests, but their performance will not be affectedfeel anxiety because of the stereotype that says they will perform well on tests, causing them to perform poorlyfeel anxiety because of the stereotype that says they perform well on tests, but still perform well despite the pressurefeel anxiety because of the stereotype that they will perform badly on tests, causing them to perform poorly4. The goal of a descriptive study is to:find a correlation between two or more variablesperform research by experimentsestablish causation between two or more variablesgather data about a given subject5. The story of Phineas Gage is a good example of a case study because:researchers determined that brain injuries do not cause emotional problemsresearchers studied him and used the information to make better hypotheses in the futureresearchers manipulated the independent variables to determine the cause of his injuryresearchers treated his case of brain injury by researching many similar studies Worksheet: Ethnographic Design: Definition, Advantages & Disadvantageshttps://study.com/academy/lesson/ethnographic-design-definition-advantages-disadvantages.html1. Which two tasks must ethnographic researchers balance when they are doing research?Looking at the big picture and having tunnel vision.Being involved in the community and keeping their distance from their subjects.Their research work and their family life.Being involved in the community and having a family life.Being involved in the community and looking at the big picture.2. What is one of the limitations of ethnographic research?It increases tunnel vision of researchers.It does not look at complex cultural phenomena.It is not interested in community experiences.It has a narrow focus on ethnic minorities.Some results can be too general to be useful.3. Why is examining complex cultural phenomena important in ethnographic research?It is important because it makes carrying out field research easy.It is important because it is necessary to get the community to open up.It is important because it helps in crunching numbers and examining crime rates.It is important because it helps the researcher to maintain a distance while getting close to the subject.It is important because it helps to strengthen the ethnographic research.4. Which of the following do ethnographic studies look at?The tunnel vision of researchers.The future of minority researchers.Individuals’ thoughts and opinions.The characteristics of a community.The ethnicity of the researcher.5. Which of the following does qualitative research examine?Ethnic minoritiesNon-numerical dataHistorical dataNumerical dataEthnic origins Worksheet: Grounded Theory Design: Definition, Advantages & Disadvantageshttps://study.com/academy/lesson/grounded-theory-design-definition-advantages-disadvantages.html1. One strength of grounded theory is:It involves collecting a lot of dataIt is less structured than traditional researchIt can produce a richer, more diverse set of answersAll are correct2. Grounded theory is called that because the _____ is grounded in the _____.Truth; theoryTheory; dataData; theoryTheory; truthNone are correct3. Which of these is NOT a limitation of grounded theory?It involves collecting a lot of dataIt is less structured than traditional researchAll of these answers are limitationsResearch bias is less likely to come into play4. Qualitative research looks at:Numerical dataNon-numerical dataHistorical dataAll are correct5. Grounded theory:Is less structured than other types of researchAll are correctInvolves collecting a lot of dataIs a type of qualitative researchOccurs when a researcher develops a theory after data is collected Worksheet: Case Study Design: Definition, Advantages & Disadvantageshttps://study.com/academy/lesson/case-study-design-definition-advantages-disadvantages.html1. Which of the following is a strength of case study research?Case studies generalize well to the world at large.Case studies allow the researcher to examine a wide range of individuals.Case studies allow the researcher to see a relationship between phenomena, context, and people.The results of a case study are hard to understand, therefore other researchers are not able to steal your results.2. Which of the following is NOT a reason to perform a case study?As pilot researchTo challenge traditional theoriesTo develop new theoriesTo prove a theory as universally correct3. Which of the following would be the best example of a case study?Bobby performs a new therapy on a small group of patients and measures how well the therapy worked.Ben gives a treatment to one group of subjects, and gives the other subjects a placebo.Jack gives a survey to every 5th person who walks into a shopping mall.Caroline visits all the middle schools in her county and gathers data from all the 6th graders.4. Richard is performing a case study, but he doesn’t record some possibly useful data because his personal opinions and preferences get in the way. This situation is an example of which of the following weaknesses for a case study?Researcher VariableResearcher BiasResearcher GeneralizationResearcher Extrapolation5. Which of the following studies would require qualitative research?Theresa wants to study how a person’s weight affects the amount of hours of TV watched.Mary wants to study how the holiday season affects the kindness of retail employees.Larry wants to study how the number of children in a family affects the amount of surplus in that family’s budget.Bobby wants to study how students’ test scores are affected by the temperature of the room in which they take the test Health Science Science Nursing NURSING 1 Share QuestionEmailCopy link Comments (0)
