Sample size matters!
When doing research, you may read news articles to get background or up-to-date information on a topic. How can you tell if coverage of an event is comprehensive and reliable?

The key thing to remember is that it's always a good idea to do some "external" searching after you read information of any kind - this means searching around for other sources that corroborate what you're reading, or provide more context.
How do you determine if the report you're reading is a reliable account?
Suppose you found this article while searching for sources for your assignment. Is it reliable? Why or why not?
