Type of analysis


For a design study, I have protocols from 5 different design groups with two persons in each team. the verbal utterance of each group (two persons) are transcribed for each sentence. and the data is driven from each line of transcription for the analysis. I want to analyze two cases:

1- I want to compare the differences between two persons in different groups.
2- I want to compare different groups functions.

which types of analysis should I take for the two above?
