CORRELATIONAL DESIGN
(General) |
STRENGTH: permits study of relationships between variables
LIMITATION: doesn't permit inferences about cause and effect relationships |
|
|
EXPERIMENTAL DESIGN
(General) |
STRENGTH: permits inferences about cause and effect realtionships
LIMITATION: findings may not generalize to actual world when in lab, and in field experiments control over treatment usually weaker than in lab; however, in natural/quasi-experiments there is a lack of random assignment that reduces precision |
|
|
LONGITUDINAL DESIGN
(Developmental) |
STRENGTH: permits study of common patterns and individual differences in development and relationships between early and later events/behaviors
LIMITATION: age-related changes may be distorted because of person's dropout, practice effects, and cohort effects |
|
|
CROSS-SECTIONAL DESIGN
(Developmental) |
STRENGTH: more efficient than longitudinal because it is no plagued by problems like dropout and practice effeccts
LIMITATIONS: doesn't permit study of individual developmental trends and age differences may be distorted by cohort effects |
|
|
SEQUENTIAL DESIGN
(Developmental) |
STRENGTH: allows longitudinal & cross-sectional comparisons that reveal cohort effect
LIMITATION: may have same problem as longitudinal and cross-sectional strategies, but design itself helps identify difficulties |
