How many are older than nine? Well, it's the one person who's 10, and then the two who are 12. So there are three. And over here, if you said how many are older than nine, well, then you would just have to go through the list and say, OK, no, no, no, no, no, no, no, no. OK, here, one, two, three. And then not that person right over there. So hopefully, this is just an appreciation for yet another two ways of looking at data, frequency tables and dot plots.
