What is a Z-Score?
A z-score (or standard score) tells you how many standard deviations a data point is from the mean. The formula is Z = (X - μ) / σ, where X is the value, μ is the population mean, and σ is the standard deviation. A positive z-score indicates the value is above the mean, while a negative z-score indicates it is below.
