Exam Review for Quasi-Experimental Designs and Longitudinal & Cross-Sectional Designs

A set of flashcards focused on key vocabulary terms related to quasi-experimental designs and longitudinal & cross-sectional research methods.

Quasi-Experimental Design

Research designs that have both experimental and control groups, but participants are not randomly assigned to these groups.

Non-Equivalent Control Group Design

A quasi-experimental design that employs nonequivalent control groups with pre and post-testing.

Ceiling Effect

A potential threat to interpretability where performance is already near the maximum, limiting improvement.

Floor Effect

A potential threat to interpretability where performance is so low that differences are hard to detect.

Delayed Control Group Design

A quasi-experimental design in which the control group's testing is deferred, leading to a non-simultaneous comparison with the experimental group.

Mixed Factorial Designs

Designs that include one between-subject variable and one within-subject variable.

Interrupted Time-Series Design

A design that allows the same group to be compared over time by considering data trends before and after treatment.

Multiple Time-Series Design

A time-series design that includes both control and experimental groups measured repeatedly over time.

Repeated Treatment Design

A quasi-experimental design comparing the same group against itself by measuring responses before and after repeated treatments.

Longitudinal Design

A within-subject repeated measurement design where a cohort is studied over a long period of time.

Cross-Sectional Design

A between-subject design where different cohorts are tested at a single point in time.

Selective Survival

A threat to internal validity occurring when certain individuals in a population can no longer be part of a sample.

Selective Dropout

A threat to internal validity where individuals dropout of a study before it ends, potentially leading to a non-representative sample.

Practice/Retesting Effects

An internal validity threat in longitudinal studies where participants get better at a test through repeated exposure.

Cohort Effect

A variable by which cohorts are grouped that confounds the independent variable.

Generation

A broader group characterized by shared traits or experiences, often influenced by unique cultural and social trends.
