Which type of validitiy deals with the question of whether a researcher generalize with confidence to a larger population in a natural setting
Which type of validity deals with whether the treatment is directly responisble for any changes observed in the experimental setting?
What is the name of the trhreat that warns researcher to be careful in generalizing the results to a populaion when an experment is conducted on a nonrandom sample?
Suppose a random sample of workers in a factory is exposed to five different reward systems, with each system being used for one month. What is the name of the threat that reminds researchers that the results may not generalize to the population of workers if the population is to be exposed to only the last reward system tried in the experiment?
Multiple- treatment interference
Suppose an experimental classroom has research observers present at all times. what is the name of the threat that reminds researchers that the results may not generalize to other classrooms without observers
