Hi,
please always remember: LimeSurvey is a data collection tool, not a statistic tool.
These things you do in your data analysis tool, where you create your cross tabs, calculate your statistical tests, and so on.
A way to do it is:
In the answer table filter your selected university
then select these and export:
In the export screen you see your selection
In my opinion the much better way is to export the entire dataset and do all filtering in your statistic tool.
