Factorial Design
|
A design with more than one independent variable.
|
|
|
Factorial Notation
|
The notation that indicates how many independent variables are used in a study and how many levels are used for each variable.]
|
|
|
Main Effect
|
An effect of a single independent variable.
|
|
|
Interaction Effect
|
The effect of each independent variable across the levels of the other independent variables.
|
|
|
Sum of Squares Factor A
|
The sum of the squared deviation scores of each group mean for factor A minus the grand mean times the number of scores in each factor A condition.
|
|
|
Sum of Squares Factor B
|
The sum of the squared deviation scores of each group mean for factor B minus the grand mean times the number of scores in each factor B condition.
|
|
|
Sum of Squares Interaction
|
The sum of the squared difference of each condition mean minus the grand mean times the number of scores in each condition SSa and SSb are then subtracted from this sum.
|
|
|
Sum of Squares Error
|
The sum of the squared deviations of each score from its group (cell) mean; the within-groups sum of squares in a factorial design.
|
|
|
Non-manipulated Independent Variable
|
The independent variable in a quasi-experimental design in which subject are not randomly assigned to conditions but rather come to the study as members of each condition.
|
|
|
Single-group Posttest-only Design
|
A design in which a single group of participants is given a treatment and the tested.
|
|
|
Single-group Pretest/Posttest Design
|
A design in which a single group of subjects takes a pretest, receives some treatment, and then takes a posttest measure.
|
|
|
Single-Group Time-Series Design
|
A design in which a single group of subjects is measured repeatedly before and after a treatment.
|
|
|
Non-equivalent Control Group Posttest-only Design
|
A design in which at least two nonequivalent groups are given a treatment and then a posttest measure.
|
|
|
Nonequivalent Control Group Pretest/Posttest Design
|
A design in which at least two nonequivalent groups are given a pretest, then a treatment, and then a posttest measure.
|
|
|
Multiple-Group Time-Series Design
|
A design in which a series of measures are taken on two or more groups both before and after treatment.
|
|
|
Cross-Sectional Design
|
A type of developmental design in which subjects of different ages are studied at the same time.
|
|
|
Cohort
|
A group of individuals born at about the same time.
|
|
|
Cohort Effect
|
A generational effect in a study that occurs when the era in which individuals are born affects how they respond In the study.
|
|
|
Longitudinal Design
|
A type of developmental design in which the same subjects are studies repeatedly over time as they age.
|
|
|
Sequential Design
|
A developmental design that is a combination of the cross-sectional and longitudinal designs.
|
|
|
Single-Case Design
|
A design in which only one participant is used.
|
|
|
Small-n Design
|
A design in which only a few subjects are studies.
|
|
|
Reversal Design
|
A single-case design in which the independent variable is introduced and removed one or more times.
|
|
|
ABA Reversal Design
|
A single-case design in which baseline measures are taken, the independent variable is introduced and behavior is measured, and the independent variable is then removed and baseline measures are taken again.
|
|
|
ABAB Reversal Design
|
A design in which baseline and independent variables conditions are reversed twice.
|
|
|
Multiple-Baseline Design
|
A single-case or small-n design in which the effect of introducing the independent variable is assessed over multiple subjects, behaviors, or situations.
|
|
|
Multiple-Baseline Design Across Subjects
|
A small-n design in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple subjects.
|
|
|
Multiple-Baseline Design Across Behaviors
|
A single-case design in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple behaviors.
|
|
|
Multiple-Baseline Design Across Situations
|
A single-case design in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple situations.
