Different Pearson's-r values when calculating correlation in JASP and R-studio
Hello
I have a very simple set of data - 39 rows, no missing data.
When I'm using r-studio to calculate person's r using cor.test, the value is 0.68.
the same data in JASP gives a value of 0.78.
Both my r-studio and JASP are up-to-date, and I calculate Pearson's r in both.
Any idea why this large difference?

The difference should be 0. Can you show a screenshot and/or upload the data file?

Sure and thank you EJ!
the "isr_exp2" is the actual data.
the "all_subject_with..." is the csv file created by the r-code (also attached).
This is also the file i used for JASP.
The correlation is between the columns "can_same" and "diff"
If I read the file you use for your JASP analysis into R, and then execute cor.test, I get the same result as with JASP:

Thanks! so I need to find out why my code gets the data from other places...
