My professor expects me to evaluate evidence in an annotated bibliography—what criteria should I actually use?

Focus primarily on the study’s methodology and sample size, as these elements directly determine whether the findings are reliable and generalizable. When you read a source, ask yourself if the research design actually tests the hypothesis or if it’s just an opinion piece disguised as data. For instance, if you’re looking at a health study, check whether it’s a randomized controlled trial or just a small survey of volunteers; the former provides much stronger evidence because it controls for outside variables. You should also scrutinize the publication date and the author’s credentials, since outdated information or lack of expertise can undermine even well-designed studies. Don’t forget to look for potential conflicts of interest, like industry funding, which might introduce bias into the results. By concentrating on these core aspects, you’ll move beyond simple summarization and demonstrate critical thinking. This approach helps you distinguish between robust evidence that supports your argument and weaker sources that might mislead your analysis. Ultimately, your annotation should briefly state what the source contributes, how it was produced, and why you trust—or don’t trust—its conclusions. This method ensures your bibliography serves as a genuine tool for research rather than just a list of citations, making your final paper much more persuasive and academically rigorous.
