Z-score : is a statistical measurement that describes how many standard deviations below or above the population mean, a specific data point's value is. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score. A Z-score of 1.0 would indicate a value that is one standard deviation from the mean. Z-scores may 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.

Formula for-score

z = (x – μ) / σ

where μ is the mean and σ is standard deviation
