What is not the purpose of peer review in science?
to validate conclusions
to conduct secret research
to check the accuracy of data
to obtain feedback from other scientists

Option (b) is the correct answer.

Explanation:

Peer review is defined as the checking someone's or a scientists's work in order to verify the accuracy of data and provide a validation to his conclusion.

For example, a man did an experiment and his friend repeated the same experiment with all the steps in order to verify the result.

When his friend verified the experiment then it means the man got a peer review.

Therefore, we can conclude that to conduct secret research is not the purpose of peer review in science.
