What is a Z score?
Z-score of raw data refers to the score generated by measuring how many standard deviations above or below the population mean is the data, which helps in testing the hypothesis under consideration. In other words, it is the distance of a data point from the population mean that is expressed as a multiple of the standard deviation.

There are the diverse application of z-score across fields if applied properly.
How to calculate z score?
Here is how to interpret z-scores: 1 A z-score of less than 0 represents an element less than the mean. 2 A z-score greater than 0 represents an element greater than the mean. 3 A z-score equal to 0 represents an element equal to the mean. 4 A z-score equal to 1 represents an element, which is 1 standard deviation greater than the mean; a z-score equal to 2 signifies 2 standard deviations greater than the mean; etc. 5 A z-score equal to -1 represents an element, which is 1 standard deviation less than the mean; a z-score equal to -2 signifies 2 standard deviations less than the mean; etc. 6 If the number of elements in the set is large, about 68% of the elements have a z-score 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.
