External validity is the ability to generalize to (and across) times, settings or persons. How would you know if your experimental research results could be generalized to the population (have external validity)? Provide an example. 200-300 words

The term that refers to the generalizability of a study is called external validity. How can an experimenter be reasonably sure that the result of his/her study which consists of a sample of the population truly represents the entire population? It is important to minimize the threats to external validity so that there is a greater assurance that the results can be generalized to the population at large. One of these is to make sure that subjects are not aware of anticipated outcomes. Doing this will reduce the possibility of this threat. Do not provide cues to the anticipated results of the study so that they don't become wise to anticipate results and they can begin to exhibit performance that they believe is expected of them. Another way that threatens external validity is ...

Solution Summary

The solution discusses the ways to know if the experimental research results could be generalized to the population or have external validity. It also explains the ethical implications of observing employees without their knowledge and its difference from observing customers. Examples and references are included.
