Influence bubbles show how correlated, or how important, a driver is to your organization's engagement score. 

A big, filled in Influence bubble indicates that the driver is highly correlated with engagement at your organization, and changes for this driver are more likely to impact your Emplify score.

Small Influence bubbles indicate that the driver is not as well correlated with engagement at your organization, and changes for this driver are less likely to influence your Emplify score.

How the score is calculated:

The influence bubble is a representation of the Pearson's correlation coefficient between the individual driver and the Emplify Engagement score for the organization within a single assessment. The circle represents the correlation coefficient for positive correlations only. The size of the bubble matches a scaled range from no (0.0) correlation to perfect correlation (1.0). Negative correlation will appear as no bubble.

The bubbles are updated for each Engagement Assessment. They are done only at the organization level and will not change as you look at different filters or groupings in your results.

In Real Life:

If your organization mostly employs at-home caregivers, questions on the Emplify survey about Co-Worker Relationships might not be as applicable to engagement for your employees. They knew when they signed up for the job they were committing to working alone and never expected to be friends with their co-workers. In this case, Friendship isn't paramount (or highly correlated) to their engagement over all, so their Influence bubble is small, even though their score is low.
