Explain how behavioral scientists deal with this problem, providing an example to illustrate your explanation.,PSYCHOLOGY

You now know that validity helps tell you if an experiment measures what you think it measures. This Application Assignment will challenge you on external threats to validity. Generalization is the underlying issue in external validity. If a research study is only valid for the sample used in the study, it is not very helpful to the study of psychology.
Suppose you were struggling with a concept in a training class at work and wanted to try a study strategy. Imagine that the Instructor in the Discussion solved the internal validity problem and found that study Strategy 1 worked better than study Strategy 2. Remember that your Instructor’s study included a population of online students. You assume that the results of this study will generalize to your training class at work. However, a replication of this study found that study Strategy 1 only works well for online students in an undergraduate program. It cannot be generalized to your in-class training course at work. Therefore, it does not generalize across settings.
The assignment: (1–2 pages)
True statement: It is not possible to know whether a research finding will generalize to all populations of individuals. Explain how behavioral scientists deal with this problem, providing an example to illustrate your explanation.
Briefly explain how the concept of generalization relates to external validity.
Briefly explain the four different types of replications and the purpose of each. Include for each an original example. Then briefly explain how replications relate to external validity.
