In statistics a z score tells us how many standard deviations away a given value lies from the mean We use the following formula to calculate a z score z X where A positive z score means the data value is larger than the mean If a data value has a z score of 2 that tells us that this data value is 2 standard deviations larger than the mean A negative z
When evaluating the sampling distribution for Z test Z score or Z statistics is defined as the number of standard deviations that the sample mean is away from the mean of The smaller the absolute value of a z score the closer a raw score is to the mean Conversely the larger the absolute value of a z score the further a raw score is to the mean

For example a Z score of 1 indicates that the observed value is 1 standard deviation from the mean A value can be above below or equal to the mean indicated by the sign of the Z score A A z score also called a standard score gives you an idea of how far from the mean a data point is More technically it s a measure of how many standard deviations below or above the
A z score is a standardized version of a raw score x that gives information about the relative location of that score within its distribution The formula for converting a raw Z scores Z value is the number of standard deviations a score or a value x is away from the mean In other words the Z score measures the dispersion of data Technically a Z score
