If that's the case then the data is not really actionable unless we also know the probability of getting a job with and without some degree.
For example, if computer science majors all tend to get job A, but having a computer science degree makes you no more likely than people without computer science degrees to get job A, then the value of the computer science degree is 0.
Of course having a degree does usually provide some advantage at getting a job, and in some fields it's impossible to get a job without a degree.
But still, for this data to be truly meaningful and actionable you must multiply the value of each degree by the amount that the degree aids you in getting a job, which is a hard value to determine.
Edit:
Here's an example of why this is important. Let's compare physical therapy and programming.
According to the data, a Doctorate in Physical Therapy has a value of about $1.2 million, while a Bachelors in Computer Science has a value of around $1.5 million.
You might conclude that the computer science degree is a better value, especially since it costs less than the doctorate.
However, you cannot be a physical therapist without the degree. So the value of the P.T. degree is $1.2m * 100%, or $1.2 million, because without the degree you have a 0% chance of getting the job (and assuming that having a P.T. degree guarantees you a job).
You can be a programmer without a computer science degree. So the value of the degree is going to be $1.5m times some percentage less than 100. In order for the C.S. degree to be more valuable than the P.T. degree you'd have to be 80% more likely to get a job than a programmer without a C.S. degree. (1.5 * .8 = 1.2)
It doesn't seem like people with C.S. degrees are 80% more likely to get jobs. Especially when you factor in the opportunity cost of going to school. That's a lot of time you could spend working on open-source projects, building websites and businesses, etc. which are all things that count more than a degree.
So the value of a C.S. degree could very easily be less than the value of a P.T. degree.
