Average inter-item correlation?

Discuss the jamovi platform, possible improvements, etc.

Hi all,
I'm teaching my students how to reverse score and conduct the various indices of reliability and validity. I must say this is incredibly easy and a joy to teach in jamovi! The heatmap of correlations is simply a godsend for demonstrating the effects of not reverse-scoring those items that are in need of this. Kudos!

However, I was wondering would it be possible to add in a feature for reliability analysis - namely the average inter-item correlation? Unless I'm very much mistaken, I can't see it? Including it so that it is automatically spat out with the heatmap would be great. At the moment I'm telling students to calculate this manually in Excel. Not a terribly difficult step I admit, but one that introduces an outside program that may not be needed....

Keep up the great work,
