The Question Correlation widget displays the relationship between two scores. Correlation factor can be overall score, section score or an individual question.
How does it work?
When two sets of data are strongly linked together they have a high correlation. The correlation range is 0% to 100%, where zero is no correlation and 100 is perfect correlation.
The strength thresholds are:
0 = none
0.1 - 20 = negligible
20.1 - 30 = weak
30.1 - 50 = moderate
50.1 - 70 = strong
70.1 - 99.9 = very strong
100 = perfect
The higher the percentage in the Correlation column, the more two numbers are related. A score of 0% means no correlation and 100% means perfect correlation. Correlation is Direct when the values increase together, and correlation is Inverse when one value decreases as the other increases.

Drilldown functionality
Selecting a row in the widget will open a more detailed correlation view, displaying the evaluations that fall into the correlation metrics filter you chose.
Selecting any of the bubbles will open an "Evaluations" pop up window, showing you a list of evaluations that belong to selected correlation filtering.
Using the left PC icon will open the evaluation in a new tab of your browser, while using the right PDF icon will create a PDF of that evaluation.
