|
factorial design |
all conditions of IV are combined with conditions of other IV |
|
|
multifactorial design |
2+ IV's provide tests of main effects as well as interactions |
|
|
Factor |
another name for IV |
|
|
Levels of experiment |
conditions in an experiment |
|
|
main effect |
the effect of an IV on DV |
|
|
interaction |
how the effect of on IV depends on the level of other IV |
|
|
why use factorial design? |
they provide more complexity. Also economical |
|
|
simple main effect |
influence of one level of IV of another IV |
|
|
before and after design |
1X observation treatment 1X observation |
|
|
subject variables |
gender, economic status, personality |
|
|
interrupted time series design |
design in which the event of interest is naturally occuring |
|
|
multi-group before & after design |
observations made before and after event of interest. |
|
|
Quasi-experiment design |
the IV is an event outside control |
|
|
individual matching |
participants matched on key factors except for IV |
|
|
aggregate matching |
groups are equivalent on average |
|
|
cross sectional design |
people of different ages compared at same time |
|
|
longitudinal design |
same individuals observed at different ages/years |
|
|
cross sequential design |
combination of cross sectional and longitudinal |
|
|
case studies |
intensive study of subject w/unusual characteristics |
|
|
single subject designs |
each participant is exposed to every level of IV |
|
|
AB design |
baseline condition precedes treatment condition |
|
|
multi-element design |
treatments repeated alternate. (not just baseline but treatments) |
|
|
Reversal/Withdrawal design |
more than one baseline condition. ABA, ABAB ect |
|
|
Multiple Baseline design |
like AB design, but staggering the Baseline length |
