I think the answers could change depending on what you want to study. But, in general, since each value of your data corresponds with one box, the units of analysis are the boxes. The observations are each value, i.e., the number of raisins in each box, and the varibales are three, 1)number of raisins in boxes of tyrant, 2) ... of acrid, and 3)... of Laminatekist.
