The number of chapters in the book "Walden" by Henry David Thoreau is discrete data.

Here's why:

Discrete data consists of distinct, separate values that are countable and typically whole numbers. In the case of the number of chapters in a book, such as "Walden," it's a specific countable value.

"Walden" has a finite and specific number of chapters that can be counted precisely. Once counted, this number does not vary—it remains constant for that particular edition of the book.
