Page 1 Questions

Please answer each of the following questions to help you self-assess your understanding of "Chapter 12: Randomized Field Experiments" (Remler & Van Ryzin, 2010)

1. (OPTIONAL) Your email address This question requires a valid email address.

2. Please Match the Term to Its Definition *This question is required.

Space Cell	Group in a randomized experiment that is assigned to receive the treatment under investigation.	The program whose effect is of interest - the cause, the independent variable, the explanatory variable, or the predictor.	Experiment in which subjects are randomly assigned to conditions (or treatments) to test for causal relationships.	An inert treatment provided to a control group in an experiment so that the experiment can be blind.	Group that does not receive the treatment being tested in a randomized or quasi experiment.	A randomized experiment conducted in an actual social or policy setting - the field.

Space Cell	Experimental design that allows for the estimation of two or more treatment effects, along with interaction effects, through arms representing all possible combinations of treatments.	The units, such as individuals or families, assigned to the treatment and control groups in a study.	The independent variables tested in an experiment, which can have main effects as well as interaction effects.	Experimental design in which the one who receives the treatment under investigation and the one who is in the control group are determined randomly.	The units, such as individuals or families, studied in an experiment.	The result of random assignment, it refers to the fact that the treatment and control groups in a randomized experiment are equivalent, on average, on all variables.	The groups in an experiment that are each exposed to different treatments or control conditions.

4. Please Match the Term to Its Definition *This question is required.

Space Cell	Experiment in which both the subjects and the research workers who interact with the subjects, or make measurements, do not know who was assigned to the treatment or control groups.	Effect of being studied on the participants in a study.	The fact that people often respond to any kind of treatment, even a completely phony or useless one.	Experiments in which subjects do not know if they are in the treatment or control group.	Measures that occur naturally or routinely, or otherwise do not disturb the subjects in an experiment.	Treatment effects that vary systematically with the characteristics of individuals.
Hawthorne Effect
Blind Experiments
Unobtrusive (or Nonreactive) Measures *This question is required
Heterogeneous Treatment Effects
Placebo Effect
Double-Blind Experiment

5. Please Match the Term to Its Definition *This question is required.

Space Cell	Randomization of convenient and natural clusters of individuals (e.g., classrooms) rather than randomization of individuals (e.g., students).	Something happens that interferes with the integrity and logic of the experiment, such as when the treatment (or elements of the treatment) is taken up by the control group.	Analysis of randomized experiments in which everyone is kept in their original randomized group - treatment or control - irrespective of compliance or attrition.	The smallest effect that would still have statistical significance in a study with a particular sample size and design, often chosen to perform sample size calculations.	The problem of participants dropping out of a study.	An analysis of a randomized experiment that provides an estimate of the effect of the treatment on those who were actually exposed to it.
Contamination
Cluster Randomization
Attrition
Minimal Detectable Effect
Intent to Treat (ITT)
Treatment of the Treated (TOT) *This question is required

6. Match the example with the research tool *This question is required.

Space Cell	The Centers for Medicare and Medicaid Services wanted evaluate whether a stop-smoking program would lower the government’s costs in providing insurance. A random group of Medicare beneficiaries were selected for a pilot program. Some of that group were randomly chosen to receive a stop-smoking pamphlet while the others received a free stop-smoking program. After two years, the agency compared the amount of money spent on medical care for each group	A university psychology department invited students to participate in a study about groupthink in the lab. By a flip of a coin, students were assigned to either receive written information and then answer a survey or talk about the information with other students and then take the survey	A study examined predictors of dropping out of high school by comparing students who did not graduate with those who stayed in school of the same race, gender, and age	A student surveyed members of the American Political Science Association. She did not have enough resources to survey all the members, so she sent her questionnaire to 100 members chosen by chance
