What counts as evidence?

The most universal way to support a point is to provide a reference to a source which backs it up: either someone who agrees with you, or evidence that supports you. As your studies progress, this strategy may need to become more in depth, perhaps referencing multiple sources or commenting critically on them. One reference is good, but might be overly selective, ignoring contradictory or better sources.

What counts as acceptable evidence will vary depending on your subject. Arts and Humanities are based in more subjective argument and interpretation; Social

Sciences often draw on qualitative and quantitative data, and Physical and Medical Sciences from empirical data. In some instances, your own personal experience can count as valid evidence, if you were writing a reflective assignment, for example, but it would not be appropriate if writing a report as it might not be representative, and cannot be verified by the reader.
