So let's say I have 10 participants per condition (2 conditions). Is it necessary to visualize for each participant per condition or is it okay to visualize a long data format of 10 participants for both condition. Here I would get 2 graphs and subsequent parameter values, whereas in the former I would have 20 graphs and values.
I would like to know what is the advantage of plotting per participant if any?
My aim is hypothesis testing btw a control and experimental condition.
