Seemingly, Lesser Degree
Quasi
Why Quasi is less powerful?
Quasi experiments CANNOT practice random assignment
An experiment without random assignment is prone to ______________.
Confounding Varibales
Confounding variables lowers _______________.
Internal Validity
Degree of certainty that the conclusion will be true
Internal Validity
Variables other than IV that mix with the effect of IV on DV.
Confounding Variable
Can we have more than one CV in an experiment?
Yes
A cause of CV?
Unequal group characteristics before the experiment
Characteristics, traits, situations, conditions, of the effects that are HELD EQUAL across all IV levels.
Control Variables
Should we equalize or control all characteristics?
No
Ways to control characteristics

- common sense
Importance of random assignment
Equalize characteristics
Random assignment is not possible in ___________________.
Quasi Experiment
