Substantiate your claims
This means every claim, argument or opinion you write needs to be substantiated (supported or justified) with credible evidence from research or other authoritative sources. You need to also explain how the evidence you present supports your viewpoint or argument.
Academic evidence usually involves expert or authoritative data, research results or statements from reputable or recognized sources, such as peer-reviewed journals.
It does NOT involve the use of information from sources that have little or no academic credibility, such as from a popular magazine, newspaper, your lecture notes, or stating personal opinions, interpretations or anecdotes without evidence to support them (unless they are specifically sought in a specific type of writing), as these are unlikely to be considered credible.

Types of Credible Evidence
There are various types of credible evidence and your selection of these will depend on the topic, the type of academic writing, and the qualities of the evidence that are valued by your discipline.
When using evidence to support your position, it is important to ensure it is relevant to the argument you are expressing and is accurate.
Six of the most frequently used forms of credible evidence are described here:
Empirical studies
Research studies that empirically test hypotheses or research questions by measuring variables and collecting and analysing data are important sources of evidence. These can be either qualitative or quantitative designs, and using observational or experimental methods.
Statistics, facts and surveys
Statistical data can be provided to support viewpoints. The sources of these need to be cited in the text.
Theory and concepts
You can support a claim or argument by reference to a theory or concepts, and then describe how this refers to a specific example in reality.
Authoritative opinions
An accepted form of evidence is the citation or quotation of a recognized authority or expert on the topic about whihc you are writing.
Examples
Examples from real life, case examples, and hypothetical examples can serve as useful evidence to clarify an argument or illustrate a viewpoint.
Quotations, testimonies, interviews
Views expressed in quotations, testimonies and interviews can be used to support your position, or emphasize a particular point. It is important to recognize that these usually come from one person and should not be overused, unless the topic calls for the presentation of this type of evidence, such as an essay or thesis that focuses on qualitative or narrative studies.
Standard English words to cite evidence
There are several standard English words used to cite evidence in order to substantiate arguments and claims. These words, often referred to as reporting words, describe the type of claim or idea that is cited from the researcher or author of the source you report in your writing.
These reporting words are verbs usually written in the past tense because they refer to opinions or research results that occurred in the past.
The 10 most frequently used reporting words are:
Believed | Found |
Suggested | Investigated |
Evaluated | Showed |
Persuaded | Explained |
Agreed | Disagreed |
Examples:
1. Smith (2011) believed that an improved theoretical framework was required to explain the phenomenon more fully.
2. Previous studies have investigated the effects of exercise on resting blood pressure in children.
3. White (2009) explained the mechanism of the action of ultraviolet radiation on cells.
