- [Instructor] Okay we're still in the ready for cluster data set. I have a smaller version of this data set, literally just fewer rows that I've already prepared, let's open it. File, open data, we're going into the resources folder and we're going to grab ready for cluster GT 60 trans which stands for greater than 60 transactions. So I've already created this file but in a later video I'll be showing you how to select a subset of data just like that. And here is the smaller file. This file has just 34 rows and as the name implies, these are all of the customers that had greater than 60 transactions. So why the smaller file, you'll fairly rarely have these few cases, it's really quite a small number. However, it's going to help us see visually how hierarchical cluster analysis works. So I'm going to go the graphs chart builder, I'm going to do a scatter plot but I'm going to do 3D scatter plot. I don't have any variables that have special status here so I can choose any variable to…
