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. 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.

Infant Nathan is smiling and "talking" with short, loud noises. His mother responds each time Nathan expresses himself by smiling and talking. This interaction is described as: <u> verbal “dialogues</u><u>”</u>.
Infants' early vocalisations (language), such as crying, cooing, and babbling, serve as the foundation upon which more sophisticated structures can be build. These high-pitched voice tones with a lot of modulation are preferred by newborns.
When speaking to a young infant, parents from diverse cultures and languages naturally utilise loud noises. In the first month, cooing noises are the first "answers" that babies make. Sometime within the first month, one of these pleasant social interactions results in these subtle vocalisations.
By the second month, the majority of babies will converse verbally with their parents back and forth in a "<u>dialogues</u>" that is cooperatively controlled by both parties.
