Experimental Validity
Experimental validity refers to the manner that variables
influence the results of the research and the generalizability of
the results to the population at large. The two types of validity
that are relevant to experimental designs include internal validity
and external validity.
Instructions:
Using a topic of interest to yourself, briefly describe a
proposed research study you would like to conduct.
Provide a detailed discussion regarding some of the potential
threats that could occur to the internal validity of your study.
Examine how these threats could reduce the validity of your
study and possibly make the study invalid.
What are some ways you could increase the internal validity?
What is the importance of external validity for your study?
Is internal validity or external validity more important for
your study?
What do you find most difficult about the idea of
validity?
What aspects of evaluating it or integrating it into research
desin are the most challenging and why?
What questions do you still have about experimental validity
after this exercise?
Your post should be at least 300 words.
