Tidy Data

There are three interrelated rules which make a dataset tidy:

• Each variable must have its own column.
• Each observation must have its own row.
• Each value must have its own cell.

That interrelationship leads to an even simpler set of practical instructions:

• Put each dataset in a tibble.
• Put each variable in a column.
