What is the difference between a report and a research essay?

There are several differences between a report and a research essay, the most important of which is that while a research essay is meant to give the conclusions of the writer, the report summarizes the conclusions of others whom the report is investigating. Stylistically, a report is always objective. The format of a report breaks it into sections and subsections, while an essay usually does not require such sectioning. It is always best, when writing for an institution or organization, to request a style guide.
