Hi, I'm Jimmy Chang, and we're here to talk about how to do a dot plot for statistics. Now a dot plot considers and compares the frequency pattern within categories or groups. And what it is in a dot plot, you have vertical dot patterns. So for example you may have something that looks like this. This is an example as to what a dot plot can look like. Now depending on the category, generally speaking each dot represents one observation. So for example this particular category got observed five times. This particular category got observed four times and this had a frequency of two and this had a frequency of one. Now you can use whatever category that you're looking for. This could be like refers to the number of fish for each color. This could be like five red fish, four yellow fish, two blue fish, etc., but the bottom line is in a dot plot in statistics each dot generally represents an observation and it's a way to kind of compare categories within each other. So it's actually a nice way to compare the data and it's pretty easy for the viewer to kind of see what's going on. So, I'm Jimmy Chang, and that's a brief glimpse on how to do a dot plot in statistics.
