Z score of 0 is the mean of the distribution.
z score is defined as z = (x-mean)/sd, where mean is the mean of the sample (or population) and sd is the standard deviation of the sample or the population. x is the raw score. z-score standardizes the data. The standardized data will have a zero mean and unit variance. It has numerous applications in statistics.
z-score of a value=(that value minus the mean)/(standard deviation)
For z-score calculation, mean and std deviation must be given.
