Z Score in Data Science
A z-score indicates how many standard deviations a particular data point is from the mean of the data i.e.
z-score of 1 means data point is One Standard Deviation from the Mean
z-score of 2 means data point is Two Standard Deviation from the Mean.
z-score of 3 means data point is Three Standard Deviation from the Mean.
If a z-score is 0, it indicates that the data point's score is identical to the mean score.
z-scores may be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean.
