Scholarly articles are the means by which scholars announce new discoveries, ideas, the results of studies, or shed new light on older discoveries or ideas.
When you integrate scholarship into your practice, your writing, or your understanding, ultimately what you are doing is taking a topic you already understand, and seeing what the latest work, study, and thought on it adds to your understanding. Scholarly articles may challenge or even overturn widely accepted truths.
Population - what population is your article studying?
Sample Size - if the article is a study, how many people did they study or survey?
Representative - how average or typical is the population being studied? Is there anything about the sample size that makes it unusual or not typical?
These sources are more focused and less general.
