Research is to ask questions, sometimes hard questions, and that sometimes challenges what other people think. They also sometimes involve real people and their opinions, through questionnaires or interviews. This all comes under the heading of Ethics. When you are dealing with people’s data, you have to be especially careful that you are doing that ethically and safely. This is a guide from the Wellcome Collection for thinking and being ethical when you are working on your EPQ. Ethics is so important that you should try to read this no matter if you think your work has ethics behind it or not.
