Chapter 2 Flashcards
Method of research using past records or data sets to answer various research questions, or to search for interesting patterns of relationships
Archival Research
Reduction in number of research participants as some drop out of the study over time
Attrition
Changes in variable cause the changes in the other variable; can be determined only through an experimental research design
cause-and-effect relationship
observational research study focusing on one or a few people
clinical or case study
Tendency to ignore evidence that disproves ideas or beliefs
confirmation bias
unanticipated outside factor that affects both variables of interest, often giving the false impression that changes in one variable causes changes in the other variable, when, in actuality, the outside factor causes changes in both variable
confounding variable
Serves as a basis for comparison and controls for chance factors that might influence the results of the study-by holding such factors constant across groups so that the experimental manipulation is the only difference between groups
control group
Relationship between two or more variables; when two variables are correlated, one variable changes as the other does.
correlation
number from -1 to +1 indicating the strength and direction of the relationship between variables, and usually represented by r
correlation coefficient
Compares multiple segments of a population at a single time
cross-sectional research
When an experiment involved deception, participants are told complete and truthful information about the experiment at its conclusion
Debriefing
Purposely misleading experiment participants in order to maintain the integrity of the experiment
Deception
Results are predicted based on a general premise
deductive reasoning
variable that the researcher measures to see how much effect the independent variable had
dependent variable
Grounded in objective tangible evidence that can be observed time and time again, regardless of who is observing
Empirical
Experiment in which both the researchers and the participants are blind to group assignments
Double-blind study
Group designed to answer the research question; experimental manipulation is the only difference between the experimental and control groups, so any differences between the 2 are due to experimental manipulation rather than chance
experimental group
Researcher expectations skew the results of the study
Experimenter bias
Objective and verifiable observation, established using evidence collected through empirical research
fact
Able to be disproven by experimental results
Falsifiable
inferring that the results for a sample apply to the larger population
Generalize
Tentative and testable statement about the relationship between 2 or more variables
Hypothesis
Seeing relationships between 2 things when in reality no such relationship exists
Illusory Correlation
Variable that is influenced or controlled by the experimenter; in a sound experimental study, the independent variable is the only important difference between the experimental and control group
Independent Variable
Conclusions are drawn from observations
Inductive Reasoning
Process of informing a research participant about what to expect during an experiment, any risks involved, and the implications of the research, and then obtaining the person’s consent to participate
Informed Consent
Committee of administrators, scientists, veterinarians, and community members that reviews proposals for research involving non-human animals
Institutional Animals Care and Use Committee (IACUC)
Committee of administers, scientists, and community members that reviews proposals for research involving human participants
Institutional Review Board (IRB)
Measure of agreement among observers on how they record and classify a particular event
Inter-rater reliability
