A z score is a numerical value that represents the number of standard deviations an individual data point is away from the mean. To calculate a z score, you need to know the mean and standard deviation of the dataset. The formula is: z = (X - ฮผ) / ฯƒ, where X is the individual data point, ฮผ is the mean, and ฯƒ is the standard deviation. A z score can be positive, negative, or zero, indicating how far the data point is from the mean.

Z scores offer several opportunities for individuals and organizations, including:
