The graph function of stata is by far the easiest to use. I also like the user-written programs can be added to the software.

I like how you can use the pull down menus or use coding to manipulate the data. The pull down menus are great when learning how to use the software. The do files make it easy to redo analysis you've done previously, and check how you've cleaned the data.

I love how fast Stata is and how easy it is to manipulate variables
