Relationship between two variables that takes on a U-shape or inverse U-shape
What is a curvilinear relationship
200
Type of comparison group developed to rule out expectancy effects

200
When people is one condition are systematically different from people in other condition
What are selection effects
200
Type of statistical analysis used when two groups are represent natural pairs or matched groups
What is a paired-samples t-test
300
When only part of full scale for one or more variables is represented in your sample
What is restriction of range
300
Type of experimental design in which a participant only experiences one level or treatment
What is a between-subjects design
300
Threat to validity in which people behave differently when they know they are being studied

Assumption that group means should be equivalent, which researchers attempt to falsify
What is the null hypothesis
400
Type of correlational analysis necessary for addressing issues of temporal precedence

400
Type of experimental design in which participants experience all levels of the independent variable simultaneously
What is a concurrent measure design
400
A threat to validity in which change occurs over time in a particular group
What is maturation
400
Method of determining quasi-experimental conditions in which only groups are distinguished based on the middle-most score

400
Research role during a study in which an actor pretends to be a participant
What is a confederate
500
Type of analysis using multiple regression to determine whether a third variable explains the relationship between two others
What is a mediation analysis
500
When experiencing one condition changes how participants respond in subsequent conditions
What are order effects
500
Type of variability in which one group or condition has consistently different experience than the other group
What is systematic variability
500
Effect that occurs when one IV’s effect on the DV depends on the level of the second IV
What is an interaction effect
500
