Common Misconceptions
How Z Score Calculation Works
To calculate the Z score, you need to know the mean and standard deviation of the dataset. The Z score is a measure of how many standard deviations an observation is away from the mean. A Z score of 0 indicates that the data point is equal to the mean, while a positive or negative Z score indicates how many standard deviations away it is.
