    "Raw score" is a datum that you are given prior to any transformation. I'm guessing that you were probably given a z-score for a data point (which you neglected to include in your question), and are trying to work backwards to determine that point's raw score. You can use this formula for z-score:



    You have values for z (I assume), the mean , and the standard deviation , so you can rearrange this to determine the value for x.
