Document Summary
Degree to which the researchers are confident that a variable made a causal inference on another. Is the iv responsible for the change in the dv? (or is there a confounding variable) Can findings be generalized beyond the present study to: Addresses similarity between experimental environment and real-world settings. Addresses degree to which experimental setting encourages participnts to behave naturally. Process by which studies are repeated to see whether original results are upheld. Experimental: pretest treatment post test. History effects: events that occur during a study that are unrelated to the experimental manipulation. Riots break out during data collection on campus. Maturation effects: people will naturally change over time no matter what happens during the experiment. Testing effects: measuring participants responses affects how they response to subsequent measures. Similar to maturation- but change is caused by the testing itself. Instrumentation effects: changes occur in a measuring recalibrated over the course of a study.
