Argumentative writing includes a thesis statement, support for the statement's position and a conclusion that uses the evidence to revisit the thesis statement, according to Purdue University's Online Writing Lab. Argumentative writing usually takes a longer form, such as an essay, but a sample paragraph could be composed of the same elements.
Argumentation is a type of discourse in which the writer researches a topic by gathering and evaluating evidence, then takes a position based on the evidence collected. The evidence may include data the writer collects or a review of published literature. The University of North Carolina at Chapel Hill Writing Center notes that the finished product should demonstrate the writer's understanding of the material and his ability to apply knowledge gained from it in new ways.
The thesis statement is a clear and concise claim. The UNC Writing Center suggests that writers draft their statements after asking identifying the point of writing their arguments.
The evidence backs up the thesis statement. Purdue University notes that evidence may consist of facts, logic, statistics or anecdotes. Whatever their form, they should represent current thinking on the subject.
The paragraph's conclusion mustn't simply restate the thesis, nor should it introduce new evidence. Rather, it should explain how the presented evidence shows the thesis statement to be true.
