An analysis of a text is how understanding the parts allow one to have a clear understanding of the whole text. An analysis usually asks how?, so what?, & why?. It helps you understand the storyline better. The biggest thing with an analysis is to eliminate opinions and base it solely upon facts. An analysis is efficient for explaining what you read and explaining it flat out to others for better understanding.
A way to use this outside of class is to use reliable sources and to not spread “fake news” or stuff that hasn’t been announced officially by the source. It can also be used by explaining a problem in parts or giving specific details so others could understand or catch up on what’s going on. Analysis could mostly be used in cases of which others will not understand what is being talked about and how to make them have a better understanding of a topic.
