The Top Correlations widget on the dashboard is a tool that you can use to quickly find the strongest relationships across all of your themes and segments.
For information on what Correlation is and how it's measured, please check out this article.
How to use the Top Correlations Widget
In the widget, you will see a pair of any combination of segments, themes, and numerical fields along with the correlation value, and frequencies of each pair value.
The correlation value on the right will show you whether a pair is likely or unlikely to be correlated. The default order of pairs is sorted by absolute values for the correlation value, but that can be changed by clicking on the title for the column.
You can configure the specific fields, the minimum pair frequency (i.e. the frequency that both components of the pair occur together), and the pair combinations to hone in on pairs that make sense to you.
The Misc Filters menu provides some advanced options for improving the relevance of correlations. It allows filtering the results with a minimum and maximum correlation and by default is set to exclude -1 and +1 correlations. These perfect correlations often occur in situations such as NPS Score = 10 and NPS Category = Promoter, which provide little or no information. Additionally, there is a filter "Coverage < 100%" that when selected will exclude pairs where either variable has 100% coverage within the pair. For example, for the pair Theme: Flight and Theme: Flight // Cancelled, the Flight // Cancelled theme will have a coverage of 100% because it is a subset of the Flight theme; as a result, it would be excluded from the displayed correlations.
For further information, hovering over any pair will give you further statistics about the pair. If you click on any pair combination that contains a theme or structured field (i.e. categorical or numerical), you will be given the option to explore the association further via the Pivot Table widget.
To understand the theme component further you can click into the Drilldown view for that theme. You can also dynamically reduce the noise in your correlations widget as you scroll through the themes. If you come across a field that you do not wish to compare you can select to exclude it from the widget.
