Module 2 Flashcards
The tendency to believe after learning an outcome, that would have foreseen it. (AKA I-Knew-It-All-Along)
Hindsight bias
What does a theory do?
It explains behaviors and events by offering ideas that organize observations.
What is a hypothesis?
A good theory that has testable predictions.
An explanation using an integrated set of principles that organizes observations and predicts behaviors and events.
Theory
A carefully worded statement of the exact procedures used in a research study.
Operational definition
Repeating the essence of a research study, usually with different participants, to see whether the basic findings can be reproduced.
Replication
A statistical procedure for analyzing the results of multiple studies to reach an overall conclusion.
Meta-analysis
A descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles.
Case study
A description technique of observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation.
Naturalistic observation
A descriptive technique for obtaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group.
Survey
A sample that fairly represents a population because each member has an equal chance of inclusion
Random sample
All those in a group being studied, from which samples may be drawn.
Population
A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other
Correlation
A statistical index of the relationship between two things.
Correlation coefficient
A research method in which an investigator manipulates one or more factors (independent variable) to observe the effect on some behavior or mental process (dependent variable).
