I'm doing a two-factor within-subject design experiment, and the two factors are all categorical variables. factor one has four categories, while factor two has two categories, and is counterbalanced. this lead to a 2*4=8 conditions. the dependent variable is a continuous variable such as reaction times.
my data is in a long format as follow
ID Trial factor1 factor2 reaction time
1 1 1 1 3.142
1 2 3 1 4.543
1 3 4 1 2.456
1 4 2 1 3.433
1 5 4 0 3.142
1 6 2 0 4.543
1 7 3 0 2.456
1 8 1 0 3.433

my first question is, is it possible to run a regression analysis? (IV: two categorical variables DV: a continuous varible)
my second question is , is it possible to run a regression analysis for the total participant (like 50 persons) as a whole as the same as a single person?
