The Z-score expresses scores on a frequency distribution in terms of a number of standard deviations from the mean. It allows for comparison of scores from different distributions and identifies the relative position of a score within a distribution. A percentile indicates the percentage of scores that fall below a particular score, an x-score is not a commonly used term, and while standard deviation is related to the calculation of Z-scores, it does not directly express scores in terms of standard deviations from the mean.
