This would be very helpful to our teaching practice as well.

I would be very happy if I could use an option between seeing the matrix as it it is now and focusing in on one option and seeing the scatter of individual results in a static state. This can be most valuable if it could be printed )or pdf) for further discussion in groups.

The matrix option can probably easily be transferred to show scatterplots. We would like to use it to give a sense of the correlation between our audience's responses on two different scales (e.g. two attitudinal scales). That would turn Mentimeter into a more powerful tool to provide simple statistical analyses in real time.

You could do mouse-over to expand the average into the individual answers.
