coding method
I know the coding , u = \frac{x-k}{h} , where k is the assumed mean and k is the scaling factor .

Normally , the k is the classwidth . What if the classwidth for every classes is different , what is k then ? Can k still be one of the classwidth , i don think that makes sense .

You have confounded h and k here, I think you mean:

"I know the coding , $u = \frac{x-k}{h}$, where $k$ is the assumed mean and $h$ is the scaling factor .

Normally , the $h$ is the classwidth . What if the classwidth for every classes is different , what is h then ? Can $h$ still be one of the classwidth , i don think that makes sense."

The coding is only a matter of convienience, it does not matter what you chose as long as it makes the arithmetic easier. If it does not make the arithmetic easier then don't code.
