In Statistics, Z-score is also known as the standard normal score which gives information about how many standard deviations are away from the mean. Generally, the positive Z score represents the raw score which is higher than the average mean. Similarly, the negative Z-score represents the raw score which is below the average mean. For example, if the standard normal score is equal to +1, it means that the one standard deviation is above the mean.
