    The Z score is the raw score in terms standard deviations (SD). It is one type of standard score, cutting off the same percentages for any normal distribution.

    Z = (score-mean)/SD

    Find the mean first = sum of scores/number of scores

    Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

    Standard deviation = square root of variance

    Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to any Z score.

    Let's say that the standardized test had 100 possible points. If we wanted to identify the top 25%, why not just select those with raw scores above 75? Why do we have to standardize the scores?
