Worksheet: Ex Post Facto Designs: Definition & Examples https://study.com/academy/lesson/ex-post-facto-designs-definition-examples.html 1. 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 exam a researcher who wants to study how obesity influences self-esteem levels in children a researcher who wants to study how eye contact influences perceptions of trustworthiness in sales professionals a researcher interested is studying how the presence of sunlight affects mood 2. An Ex Post Facto design is considered to be quasi-experimental. Why? the dependent variable is the same for all groups in the experiment participants are randomly assigned in this kind of experiment the experiment is being used to study health psychology participants are not randomly assigned in this kind of experiment 3. 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 study a true experiment randomly assigning participants to experimental and control groups controlling variables that could influence one another an experiment with an ex post facto design 4. 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 group they do not have access to a control group they want to study something you can’t ethically or physically control they plan to study only one variable 5. An Ex Post Facto design is most often used with, but not limited to, which of the following types of experiments? developmental psychology clinical psychology behavioral psychology health psychology Worksheet: Pretest-Posttest Design: Definition & Example https://study.com/academy/lesson/pretest-posttest-design-definition-example.html 1. When do researchers generally notice the practice effect? Only occurs when you use the exact same tests with each subject multiple times Participants answers change due to familiarity with questions or tasks Participants are able to complete tasks faster due to prior experience doing the task in real life Participants score 100% on tests with some coaching from the study designer 2. 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 tasks How to better design questions and tasks The specific effect on the individual A focus on group processes 3. Why is pretest-posttest design referred to as quasi-experimental? Study participants are assigned to control group The effects on participants are not monitored carefully Study participants are asked to provide feedback on the study design Study participants were not randomly assigned 4. 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 depression The practice effect of the manipulation led to strong depressive tendencies Most of your subjects were already borderline depressed Working with you causes depression in most people 5. 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 Psychology https://study.com/academy/lesson/types-of-research-designs.html 1. 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 study Descriptive research Correlational research Experimental research 2. 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 linked as intelligence increases, income increases as intelligence increases, income decreases the correlation between intelligence and income is insignificant 3. 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 affected feel anxiety because of the stereotype that says they will perform well on tests, causing them to perform poorly feel anxiety because of the stereotype that says they perform well on tests, but still perform well despite the pressure feel anxiety because of the stereotype that they will perform badly on tests, causing them to perform poorly 4. The goal of a descriptive study is to: find a correlation between two or more variables perform research by experiments establish causation between two or more variables gather data about a given subject 5. The story of Phineas Gage is a good example of a case study because: researchers determined that brain injuries do not cause emotional problems researchers studied him and used the information to make better hypotheses in the future researchers manipulated the independent variables to determine the cause of his injury researchers treated his case of brain injury by researching many similar studies Worksheet: Ethnographic Design: Definition, Advantages & Disadvantages https://study.com/academy/lesson/ethnographic-design-definition-advantages-disadvantages.html 1. 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 minorities Non-numerical data Historical data Numerical data Ethnic origins Worksheet: Grounded Theory Design: Definition, Advantages & Disadvantages https://study.com/academy/lesson/grounded-theory-design-definition-advantages-disadvantages.html 1. One strength of grounded theory is: It involves collecting a lot of data It is less structured than traditional research It can produce a richer, more diverse set of answers All are correct 2. Grounded theory is called that because the _____ is grounded in the _____. Truth; theory Theory; data Data; theory Theory; truth None are correct 3. Which of these is NOT a limitation of grounded theory? It involves collecting a lot of data It is less structured than traditional research All of these answers are limitations Research bias is less likely to come into play 4. Qualitative research looks at: Numerical data Non-numerical data Historical data All are correct 5. Grounded theory: Is less structured than other types of research All are correct Involves collecting a lot of data Is a type of qualitative research Occurs when a researcher develops a theory after data is collected Worksheet: Case Study Design: Definition, Advantages & Disadvantages https://study.com/academy/lesson/case-study-design-definition-advantages-disadvantages.html 1. 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 research To challenge traditional theories To develop new theories To prove a theory as universally correct 3. 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 Variable Researcher Bias Researcher Generalization Researcher Extrapolation 5. 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
