Once patterns and outliers emerge in type 1 data the question that naturally

### Data You Don’t Know You Need to Know (type 3)
By interacting with data in real-time while using appropriate visual analytics,
Tableau provides the possibility of seeing patterns and outliers that are not visible

yields different questions that can lead to new actionable insights. Software
that enables quick-iterative analysis and reporting is becoming a necessary
element of effective business information systems.
Distributing type 1 reports in a timely manner is important, but speed in the

tool must adapt quickly to ad hoc queries and present the data in intuitively
