What is a 'Z-Score'. A Z-score is a numerical measurement of a value's relationship to the mean in a group of values. If a Z-score is 0, it represents the score is identical to the mean score. Z-scores may also be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean. Positive and negative scores also reveal the number of standard deviations the score is either above or below the mean.
To calculate a z score, you just divide the scores deviation from the mean by the standard deviation. In our example, if your consumption is 1000 Calories more than the mean and the standard deviation is 100, then your z score is 10, because (4000 - 3000) / 100 = 10. But if the standard deviation is 1000 then your z score would be 1. A z score is the number of standard deviations a data point is away from the mean. For a population of scores: .
