Explanation:

In the process of gathering data for analysis, it is very important that certain ethical standards are adhered to. One of these very important ethical requirements is making sure that there is consent from the individuals whose data is to be used. Individuals have a right to their privacy. Using data or information about them for whatever purpose without them approving of it is a breach of privacy and might incur lawsuits if they get to know about that.

To prevent such issues from arising, the intent of the analyst should be clearly disclosed and the approval of the informant obtained.
