 * The term "population generalizability" refers to the extent to which the results of a study can be generalized to the intended population.
 * The term "ecological generalizability" refers to the extent to which the results of a study can be generalized to conditions or settings other than those that prevailed in a particular study.

from Marcie's slides (wk 3)



from Marcie's study session: (generalizability means external validity)

external validity is generalizability: looking how a study is generalizable to another group or place

external: your results have broad applicability than what you intended two types: population (broader app. to other people) and ecological (broad app to other settings: like headstart on east and west coast)
