The z-score is the number of standard deviations while the data value is away from the mean.
The Z-score is said to be a kind of numerical measurement that is known to show or depicts the value's relationship one has to the mean of a group of values.
WE have given a mean: 4.9 median: 6 mode: 6 variance: 4
The Z-score is often measured usually in terms of standard deviations that arise from the mean. It means that if a Z-score is 0, it shows that the data point's score is the same as the mean value.
