Internal and External Validity

2 Nov

How can we generalize the results, to whom? and under what circumstances (external validity).

Is the treatment responsible for the changes we observe (internal validity).

Think of the design for your lab 3 and lab 4, what are possible threats to internal and external validity?

    Dear Professor Striano and class,

    I see only 1 threat so far to our study, as discussed in class today it is generalization, which for our experiment would probably be impossible since we are only looking at Hunter College students.
