JASP is an open-source statistics program that is free, friendly, and flexible.
Armed with an easy-to-use GUI, JASP allows both classical and Bayesian analyses.
Next to nearly all classical analyses that are available in programs such as SPSS, as well as their Bayesian counterparts, here are some of the main features of JASP:
great tool! Except I can't open any files because the roll app is ot up to date and there is not other version.
Missing functionality to add variables to a data frame and to edit values in the cells. You need to upload your data in it's final form, but if I have to edit my data file in some other app first, it kind of defeats the purpose.
I cannot open Jasp files for my class because this version is out of date! PLEASE UPDATE!! if i pay then it needs to work. I am very unhappy.
I cannot open a lot of data files sent to me by my research partners who are using the downloaded version because the browser version is not updated. It is incredibly frustrating. It's a great app but has so many drawbacks compared to the "real" version that I can't recommend it. Please update!!
After I figured out how to upload files, it worked great. For those who were stuck, you need to connect your account to a cloud storage drive (e.g., Google Drive, Dropbox) in your rollApp settings. Then you can open files from that drive. The big downside of this version is you can't save your output unless you have the premium rollApp account, but you can run your analyses.
