Answer: unreliability
Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.

That is, it does not reflect the ratings of a larger population. This problem can be solved by increasing the sample size, such that the average ratings are more reflective of a wider audience.
Validity considers the accuracy of the experiment. A lack of reliability of an experiment will likely make the result invalid as well, but this is not always the case.
