    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.
