The importance of using reliable sources

Just because something has been posted online or in print does not make it wholly as a source of information.

When you are conducting research (whether for an essay for English, Art, Science or another subject) you should aim to access the best quality sources possible. This will require you to the source that you are reading and to decide quickly whether or not the information within this source will support and improve your essay.

How to evaluate a source

To evaluate a source, begin by asking yourself:

  • Who has written/published the information?
  • What information are we being given?
  • Why has this information been written/published?

Evaluating a source gives you confidence in the quality of the information that you are being given.

Questions to ask yourself when using a source in your essay

¸é±đłľ±đłľ˛ú±đ°ů…

We are surrounded by many different sources of information, not all of it is accurate or reliable. In particular, anyone can post information online, so it is important to be able to work out who we should be listening to/believing.

Who?

Which of the listed people or organisations in the box below are considered reliable sources of information?

  • A journalist
  • A blogger
  • An expert in the field
  • A registered organisation or charity (an organisation/charity that has been legally registered with the government and follows certain rules and regulations)
  • A government agency
  • An anonymous author
  • A vlogger
  • A reviewer

What?

The next step on evaluating a source is thinking about what information we are given in it.

Here are some examples of types of information we might come across

Type of informationDefinitionExample
StatisticsCollecting, analysing, organising and presenting data.'59% of UK households reported owning at least one type of pet.' (Source: Statista)
Views of expertInformation from a person with specific knowledge of a topic or field.'An expert from The Royal Veterinary College says…'
AdvertisementMedia that encourage you to buy things or have a particular point of view. Remember, advertisements will often give positive information that will require balance.'This is the best dog food in the world!'
Factual informationInformation that deals with facts, not opinions. For example, factual information could come from an encyclopaedia entry.'A dog is a domesticated carnivorous mammal.'

If you find a statistic you want to use, think carefully about how you are going to use that statistic to add value to what your own argument.

In your essay, you will have to explain the importance of the evidence that you have found. Make sure that you fully understand:

  • what is being conveyed
  • why a writer has included it

Why?

A final consideration we must make in evaluating a source is thinking about why that source has been produced.
