# What is Tidy Data?

## The simplest definition of tidy data.

Posted on January 25, 2022 • Tags:

The definition of “tidy data” is simple:

1. Every column is a variable
2. Every row is an observation
3. Every cell is a single value
4. Each table is a dataset

Tidy data is equivalent to “third normal form” (3NF) in database-speak.
