We can convert any normally distributed population to standard normal distribution using zscores. The z score is z = (xμ)/σ where For example: Find the zscore corresponding to a raw score of 132 from a normal distribution with mean 100 and standard deviation 15. z = (132100)/15 = 32/15= 2.133 Our new raw score is 2.133. Hope this helps, Janice
