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.

What term describes people who share similar characteristics but little else, such as all women attending college, all left-hand
ser-zykov [4K]

A category describes people who share similar characteristics but little else, such as all women attending college, all left-handed people, or all men over seven feet tall.

<h3><u>Explanation:</u></h3>

It is described as group or class or division of people who share similar characteristics. For examples in the questions all women attending college is a category of women with similar characteristic of attending college and it excludes any other women who don’t attend college. Categorizing is important since it adds more details to an existing category.

Instead of the general category of “all people,” a more specific categorization such as “all left-handed people” further provides additional information excluding people that are not left-handed. In addition, categorization provides a distinction between similarities and difference.
