Subject: How are fingerprints read?

We are studying the scientific method in class and were trying to predict the 
most common fingerprint type in our class. When we stamped our thumbprints on 
the paper, my right thumb looked like a right loop, but when I look at my 
thumbprint on my hand it looks like a left loop...which is correct? Is it right 
loop or left loop?

Thanks for clearing up the confusion!
