Question

in one or two paragraphs explain why we need an ethical review of secondary data before one can conduct data analysis.

Answer 1

The secondary data refers to the use of existing research data to gegerate new hypothesis or to find the answer of critical problem.

We need an ethical review of secondary data for the purpose of confidentiality and security. Freely available data on the Internet need permission for further use in secondary data analysis. Ownership of original data must be mention. If data is not freely available we need written permission from original research team and this also included application for ethical clearance.
