Answer to Question 1

A

Answer to Question 2

D
Feedback:
The history threat is the occurrence of events concurrent with the independent variable that can affect the outcome. The maturation threat arises from processes occurring as a result of time (e.g., growth, fatigue) rather than the independent variable. The selection threat reflects biases stemming from preexisting differences between groups. RCTs have a clear superiority for testing causal hypotheses. Internal validity is the extent to which it can be inferred that the independent variable is truly causing the outcome.
