I am working on my thesis right now and am having trouble creating the right graph for my data.

I have two conditions (1-public, 2-Montessori) and a set of values based on the score of the children that is either a 0 or 1.

I need to create a histogram showing how many children got a 0 and how many got a 1 for each condition. In total there would be 4 bars - condition 1 (0s and 1s); condition 2 (0s and 1s).

Does anyone have any idea how to do this?
