Being sure is good; being uncertain is not necessarily bad. Research teams are working to render uncertainty visual.

via Data visualization: ambiguity as a fellow traveler : Nature Methods : Nature Publishing Group.

The visualization platform Caleydo has a functionality called StratomeX that reveals uncertainty factors in data analysis. Shown here, different clustering algorithms used to slice through the same brain-tumor gene expression data lead to different results. Algorithms: non-negative matrix factorization method (left), consensus hierarchical clustering method (center) and consensus hierarchical clustering method after manual curation of the data (right).

This paper looks at the uncertainty in statistical analysis and how differing results and data uncertainties can affect how we ‘read’ data.

To do: check out consensus clustering etc.
