The purpose statement is typically found at the beginning of the book or article, usually in the introduction or preface. It should be concise and to the point, and it should give the reader a clear understanding of what to expect from the work.
Here are some examples of purpose statements:
Example 1: "The purpose of this book is to provide an introduction to the history of the United States for high school students."
Example 2: "This article examines the impact of climate change on the Arctic region, with a focus on the Inuit population."
Example 3: "This research study investigates the effectiveness of cognitive behavioral therapy (CBT) in reducing anxiety in college students."
A well-written purpose statement can help readers decide if the book or article is relevant to their interests and needs, and it can also provide a framework for understanding the rest of the work.
