circular statistics
Dear Colleagues ,
I have conducted a tapping experiment, examining beat production and I have to analyze participants' tapping data (csv files) . Since there is a great variability, I must use circular analysis.
I have downloaded the Circular module and already examined the example which is included.
It seems a little bit complicated to me, how I could organize my data in order to be able to analyze them.
I have conducted a tapping test, in 3 different tempi (slow, medium, fast) three times (pre-test, middle-test and final-test).
Each time, participants completed each task (slow, medium, fast) twice.
So, my dependent variables are the performances in the different tempi, and I want to compare the two measurements of each task both within the same time (pre, middle, final) and between each time.
There is a reference .csv file for each tempo. Taps of the participants are always off-beat. How can I present this difference using the circular analysis in JASP?
I am sending an example .csv file for 500 BPM. The data are from one participant in the two measurements only for the pre-test.
How can I include the inter-stimulus interval and appreciate the synchronisation consistency of each individual?

Hi Marthapapa,
I'm afraid that I have never used circular statistics myself. I think I can only advise you to talk with an expert for this particular analysis (it was a contributed module, so the other JASP team members are not experts either I think). Maybe someone else on this forum?!
Cheers,
E.J.
The classic text on circular statistics is Circular statistics in biology by Edward Batschelet. This is old (1981) but a copy should be found in any University library.
Abbreviated but helpful introductory information can be found here https://ncss-wpengine.netdna-ssl.com/wp-content/themes/ncss/pdf/Procedures/NCSS/Circular_Data_Analysis.pdf
I am just starting to think about using circular stats for a particular data set so I also am a beginner here - sorry not to be more helpful.

Thank you very much for your responses! I have searched a lot the last 6 months, and I could say that I have somehow understood how it works. But I cannot work on Matlab, and I was excited that a statistical analysis could be finally completed in JASP. Thank you!
Still, I have no clue how I should import my data in order to get the proper values and be able to analyze the results.
Should I build new columns with their raw data, or would it be possible to import the means and absolute means, as well as the SDs that I have already extracted from the matlab code?
all the best!

Hello community,
I am using Mac Mojave and I had the Jasp 0.16 older version . Suddenly, it does not open . I have downloaded the older version 0.15 to try something else, but it is not working either.
The problem is that I have all my PhD statistics there!
Is there anything else that I should try?
Thanks!
Please post the issue on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/), and the programming team can take it from there
