# Ranking Things Properly

I keep seeing things ranked improperly, so here is how to do it right.

Imagine that we have six candidates for an exam, and they score as follows. Ranking these candidates is very easy.

 Name Score Rank Abel 90% 1 Bohr 80% 2 Curie 70% 3 Dirac 60% 4 Einstein 50% 5 Feynman 40% 6

But what if two candidates have the same score? The correct way of ranking is to give both of these candidates the same rank, but then the next rank is one place lower. In the example below, Abel and Bohr both score 90% and are therefore ranked in first place; Curie then remains in third place, rather than being elevated to second.

 Name Score Rank Abel 90% 1 Bohr 90% 1 Curie 70% 3 Dirac 60% 4 Einstein 50% 5 Feynman 40% 6

This prevents a situation in which we have six participants, but the person with the lowest score is ranked fifth. If more than two participants have the same score, or if this situation occurs more than once, the same rule is applied.
