When I was using data.world, it only allows me to have up to three data sets at a time unless I upgrade my subscription and pay $12/month. I set up my account the same way as they showed us in the video and it was my understanding that this was a free service, or one that I could access for free as a student. I am willing to pay for the service, however I am wondering if there was some type of student access I was missing.
So the data.world account we use is the free version and there is no student version, I’m sorry about that! That being said you can add multiple sheets to one data set so hypothetically you shouldn’t need to buy the service, the free account should be good enough. Let me know if you have any difficulties with that, good luck!
