Question: Which of the following scenarios would represent a lack of validity in a sociological experiment?

A. A different sociologist conducts the same experiment and their results are drastically different.

B. A sociologist skips a part of the experiment and instead estimates a quantitative factor rather than verifying it.

C. A sociologist whose parents were killed by a heroin addict sets out to prove that drug addicts are a great threat to society.

Sociological experiments can lack validity due to issues such as external validity concerns, estimating quantitative factors instead of verifying them, and conducting experiments with biased agendas.

Explanation:

External validity issues can arise in sociological experiments when the conditions of the experiment do not accurately represent real-world scenarios outside the lab. This lack of validity becomes evident when a sociologist estimates a quantitative factor without proper verification, which could lead to skewed results. Additionally, if a sociologist conducts an experiment with a biased agenda, like aiming to confirm personal beliefs rather than seeking objective truth, it would introduce a significant threat to the experiment's validity.
