aggregation over groups vs. rounds

I have an experimental design where I have 10 groups and within each group there are 10 people. Each subject answers 12 questions five times.

I want to plot graphs to see how each group performed and in one case, I need to aggregate over groups and in another one over rounds. The aggregation method I'm using is median.

Could someone explain to me what is the difference between aggregating between groups versus rounds? If I were to plot the data, how would it look roughly?

Any help is appreciated. Many thanks!
