According to the pictograph below, how many survey respondents have type O positive blood? How many have O negative blood? So a pictograph is really just a way of representing data with pictures that are somehow related to the data. So in this case, they give us little pictures of, I'm assuming, blood drops right over here. And then they tell us that each blood drop, each blood drop in this pictograph represents eight people. So you can kind of view that as a scale of these graphs. Each of these say eight people.
