Experimental Design
The variable that is manipulated.
What is the Independent Variable?
An equal number of people fall on either side of it's center line.
What is a Bell Curve?
True or False: Researchers can share the results of the study with the participant's names still attached.
FALSE! Confidentiality
Otherwise known as the "I knew it all along" phenomenon.
What is Hindsight Bias?
The simplest way to gather a large amount of data.
What is a Survey?
In a double-blind experiment, these people are unaware of the critical aspects of the experiment.
Who are the Participants and the Researchers?
In an experiment, what variable should yield results?
Dependent Variable
ensure that participants will not be caused distress, both physical and emotional.
Protection from Harm
A bias that causes people to assume others agree with my belief.
What is the False Consensus Effect?
Involves recording factual, behavioral data without altering anything in the environment.
What is Naturalistic Observation.
If a population is all those in a group being studied, from which random samples may be drawn, what is a sample?
The group of people used in a study
"As studying increases, sleep decreases," represents this type of correlation
What is a Negative Correlation?
giving potential participants enough information about a study to enable them to choose whether they wish to participate.
informed consent
73% of U.S. drivers believe they drive better than average.
What is Overconfidence?
An in-depth analysis of a single person or small group.
What is a Case Study?
Aside from being a a set of procedures, what is the purpose of an Operational Definition?
To be able to replicate the experiment
Calculate the mean of this data set:
15, 10, 14, 15, 11
13
Must grant approval before an experiment can be conducted.
What is the Institutional Review Board?
Tendency to pay attention to information that supports ones beliefs.
What is Confirmation Bias?
This research method is most likely to be used to determine a cause-and-effect relationship between variables.
What is the Experimental Method?
What is Random Assignment?
Clear, measurable descriptions of variables and procedures.
What is an Operational Definition?
Treat in a humane manner, legally obtained, have a clear purpose and cause the least amount of suffering possible.
What are ethical guidelines for using animals in experiments?
Th unintentional influence of the experimenter's expectations on the research they are conducting.
What is Experimenter Bias?
Relies on numerical Data
What is quantitative research?
These components make a research method Experimental.
What are Random Assignment of Groups
and/or
Use of Independent Variables
Research method involving analysis of 50 different studies that all focus on the same issue/topic.
What is Meta-Analysis?
If you use deception in your experiment, you must complete this ethical guideline to remain ethical.
