External Validity Quiz

Q1: External validity refers to the extent to which:

• A) The study measures what it intends to measure
• B) The results of a study can be generalized to other settings, populations, and times
• C) The study controls for all possible confounding variables

Q3: Ecological validity is concerned with the extent to which:
