How does humidity affect conductivity of air?

I am asking this that because I read that dry air is better insulator than normal air.

Do you find some graphs when you Google the subject?

Are you talking about thermal conductivity or electrical conductivity?

I was talking about electrical conductivity.
Just after I submitted this thread I found the answer in another page I was reading.
http://www.physicsclassroom.com/clas...and-Insulators
i.e.
Water has a tendency to gradually remove excess charge from objects. When the humidity is high, a person acquiring an excess charge will tend to lose that charge to water molecules in the surrounding air. On the other hand, dry air conditions are more conducive to the buildup of static charge and more frequent electric shocks.
