Finally, a concluding statement is made  that summari+es the main results of the lab and states whether the e)(erimental hy(othesis was correct or not. #his section of the lab write-u( is very similar to the structure that is used to write a -(aragra(h essay in your writing class. Like an essay, an “analysis and conclusion” includes an introduction section, a main body, and a conclusion.
