One way to evaluate information is with the C.R.A.P.Test. Ask yourself questions about the sources' Currency, Reliability, Authority and Purpose/Point of View.
Use the C.R.A.P. Test to determine if your source is credible.
When doing your research did you find conflicting opinions? This is the result of divergent problems, meaning there is more than one answer to a problem. In academic research you will rarely find that everyone agrees with each other. You need to look at the information you have found and think about what supports your argument, but you can't ignore the information that disagrees with your point either. Use your research to support your opinion and show why you disagree with others. You need to use use both supporting and disagreeing information in a good research project.
