Internal validity is the extent to which a researcher is confident that no other variable(s) except those being studied caused the results. While internal validity is related to cause and effect therefore the experimental method, some individuals use the term to indicate a well-designed methodology in general. There are common threats to internal validity an evaluator should be aware of to better design a quality evaluation methodology.
At the beginning, of your response, briefly summarize your program evaluation and then:
1. Discuss the importance of internal validity to the program evaluation process.
2. Identify at least three potential threats to the internal validity of your program evaluation. Explain your reasoning for why the threats exist.
3. Recommend strategies to address the identified potential threats and lessen their impact on the program evaluation results.
