The mean score for Class A is 75, with a standard deviation of 10, while the mean score for Class B is 85, with a standard deviation of 15. You calculate the z-scores for both classes and get the following results: Class A: z = (80 - 75) / 10 = 0.5 Class B: z = (80 - 85) / 15 = -0.33. In this case, you might choose to round the z-scores to two ...What is a Z-Score? The Z score itself is a statistical measurement of the number of standard deviations from the mean of a normal distribution. In the world of statistics, numbers and data are gathered, organized and compared in order to derive information and patterns. One of the ways that this is done is by the use of the z-score.
