Z-score can be computed by subtracting the mean from the given standardized random variable value and then divide by the standard deviation. * If we get negative z-score that is below the mean; * If we get positive that is above the mean; * If we get zero that is same as the mean. Let us consider an input data 2,3,4, the sample mean for the given value is 3 and standard deviation is 1, Consider the standardized random variable as 5, By substituting the given values in the formula, ( 5 - 3 ) / 1 we will get the z score value as 2 We got a positive z value (2) so that's above the mean.
