Explanation:

According to my research on different experimental dilemmas, I can say that based on the information provided within the question this is a clear example of a term known as Experimenter Bias. This is the process where the scientists performing the research influence the results, in order to portray a certain outcome. Miriam is doing this by excluding a certain group from her research, therefore affecting the results.
