Here's a program in R that runs in the cloud and produces a CSV file with a table showing the most popular college majors and average earnings by major for any occupation.
UPDATE: Here's a video showing you how to use the program!
You can get a free Posit Cloud subscription and try out R without having to download R software or any data.
I tried to make running the code as easy as possible so someone with no experience with coding can run it, and then modify the code and rerun it. A user can select any occupation. Depending on what occupation they pick, it is quite possible no one has ever carried out the analysis before, so this program gives the user a chance to do real, original research. (In fact, the program generalizes the analysis done by John Winters in, "Is economics a good major for future lawyers? Evidence from earnings data," published in The Journal of Economic Education in 2016.
The instructions for using the file are embedded in the first lines of the code to the program linked to above, so click the link and give it a try today! Please leave a comment if you do!
