3
New cards

clinical trial results may look different in DC than Mississippi because age/demographics/ lifestyles/etc. are different

why is a randomized control trial essential for generalization?

4
New cards

empirical evidence

the only means by which scientists can corroborate, modify, and construct scientific theories

5
New cards

antecedent (confounding) variable

creates a spurious relationship between X and Y (can be eliminated through a control)

6
New cards

intervening variable

can explain some part of the relationship between X and Y (Z variable), where you live, secondhand smoke, age, family history etc.
