Join Barton Poulson for an in-depth discussion in this video Association analysis in Orange, part of Data Science Foundations: Data Mining.
- [Narrator] The first thing we need to do…is we need to actually read the data in.…So I come over here where I can get my various…widgets or bits and functional operating bits,…and I'm going to drag in file.…Double click on that and let it know I want to read…this file.…You simply click on the folder and you tell it which one.…I want that one, I mean it's already what was there.…We will hit reload just to make sure its got it.…It has a 1,000 cases which is what it's supposed to have,…50 features or 50 different items that people…could purchase and it has zero meta attributes.…Which is fine for this data set.…
I'm going to close that and just so we know…what we are dealing with,…I'm also going to drag in this item data table.…That we we can sort of see what we have,…and I'll sort of drag from this corner to this corner.…Then when we open up data table, you can see that…we've got the question marks for the missing data.…You see the one's in there, there are a few of them…but that makes it possible to represent the data…
