This might be a basic question, but I have a dataset that measures items on 3 distinct measures (say time, speed, and distance). I’m attempting to find a combined ranking of these. Is it acceptable to take the quartile ranking of each measure and then find the average quartile ranking across the three measures?

In other words one item might have quartile rankings of 1 (time), 2 (speed), and 3 (distance). The average quartile ranking would then be 2. I’m just not sure if that’s something that’s done or shouldn’t be done.

Thanks for any help!
