z-score calculator a z-score aka a standard score indicates how many standard deviations an element is from the mean a z-score can be calculated from the following formula z x where z is the z-score x is the value of the element is the population mean and is the standard deviation here is how to interpret z-scores a z-score less than 0 represents an element less than the mean a z-score greater than 0 represents an element greater than the mean a z-score equal to 0 represents an element equal to the mean a z-score equal to 1 represents an element that is 1 standard deviation greater know more about gcf calculator

than the mean a z-score equal to 2 2 standard deviations greater than the mean etc a z-score equal to -1 represents an element that is 1 standard deviation less than the mean a z-score equal to -2 2 standard deviations less than the mean etc if the number of elements in the set is large about 68 of the elements have a zscore between -1 and 1 about 95 have a z-score between -2 and 2 and about 99 have a z-score between -3 and 3 here is another way to think about z-scores a z-score is the normal random variable of a standard normal distribution learn more about significant figures calculator
