Ideas in this flowchart

• Tidy data are organized in a rectangular structure.
• The rectangular structure assigns clear roles to columns and rows.
• Each column represents a variable.
• Each row represents an observation.
• Data become difficult to analyze when their structure is inconsistent.
• Multiple variables are mixed in one column.
• The same variable is spread across multiple columns.
• Columns contain different numbers and types of values.
• Converting data into tidy form makes it easier to sort, filter, summarize, and analyze with software.
