    You have provided no useful information with your post. Provide a few more details and what you tried already and possibly you can receive some help.

    Transform the thing and then do a 35,000′ management report. Don’t
    worry if it makes any sense at all.Tell them you learned it from Forrest.

      The easiest way to deal with problems of this type is to use the Finagle Phudge Transform Factor – take the data, multiply each data point by 0, and add a number from a normal random  number generator to the result.  The data will now be normally distributed and you can apply any test requiring normally distributed data.

    The Finagle Phudge Transform Factor has worked reasonably well for us in the past. I would think that should be your first choice of a transformation method.

    Pari –   By knowing that your data is Non normal – you have already analyzed your data.  That being said, – want are you figure out?    Most of the stat package tools are sensitive enough that the normality of the data is not as critical as a lot of people would like to think.   Stevo
