I try to find out if there is an influence of the age (1=young, 2=old) on the appreciation of the music style.
Question : Does the age influence the average most appreciated music?

(i can't upload data as a new user so there is a link to a pdf)
Which test should I use, and how to process with R studio?
Thanks a lot.
