Transform set of raw scores to percentile ranks

[PatWilliams]

Can anyone suggest a formula to transform a set of raw scores to their percentile ranks?

Hey @PatWilliams,
if your variable is (e.g. scores), you can compute a new variable (e.g. percentile_rank) by entering this:

Code: Select all

RANK(scores)/VROWS(scores)

I am also attaching a jamovi file as a small example, where I also used Rj editor+, with some lines of R code, to obtain
as already suggested above (computed variables), but also the percentile ranks for a group variable present.
