I know what it is, how it works, etc... but in my science lab, we have to count kernels of corn and discover the genetics behind it. This means that there are really huge degrees of freedom because each kernel can be its own color. Anyone have a chi square table that goes up to over 700 degrees of freedom? Or, anyone know a web tool to give it the degrees of freedom and have it spit out the table for that row?

OR, is there a way to figure it out sans table? Thanks.
