Why is population validity especially problematic for anderson and dill (2000)'s study 2? the sample varied too much. the internal validity was too low to generalize results to the population. the participants were all undergraduate students. the sample was too small?

The problem on Anderson's and Dill study is that the participants were all undergraduate students.

texas governor sam houston opposed secession, but was unable to prevent it. in this speech, given prior to lincoln's election, he presents the argument that slavery would be safer within the united states than outside of it. it was a prescient argument, and one held by several other southern leaders.
