Standard Score
In statistics, a standard score is a dimensionless quantity derived by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation. This conversion process is called standardizing or normalizing; however, "normalizing" can refer to many types of ratios.
Standard scores are also called zvalues, zscores, normal scores, and standardized variables; the use of "Z" is because the normal distribution is also known as the "Z distribution". They are most frequently used to compare a sample to a standard normal deviate (standard normal distribution, with μ=0 and σ=1), though they can be defined without assumptions of normality.
The standard score indicates how many standard deviations an observation is above or below the mean: the standard deviation is the unit of measurement of the zscore. It allows comparison of observations from different normal distributions, which is done frequently in research.
