Answer: unreliability
Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.
Reliability considers the consistency of the experiment. In the example above, the result of the second sample is inconsistent with the result of the first sample, making Watt's research unreliable.

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.
