This chapter describes the art of crafting empirical, data-rich chapters that are found in nonfiction. Given that facts form the backbone of nonfiction, the challenge lies in presenting them in an informative and approachable manner. The selection of data precedes its utilisation in the book. The type of data deemed necessary is contingent upon the book’s subject and the discerning choices of the writer. Unorganised and clumsy presentation of data in nonfiction can deter readers. A balance between data and words must be maintained in nonfiction, considering both the total word length and their appropriate proportions. The chapter offers lessons on creating data-driven chapters with an engaging style that integrates with the text.
