For example, let's say we have a dataset of exam scores with a mean of 80 and a standard deviation of 10. If a student scores 90 on the exam, we can calculate their Z score as follows: Z = (90 - 80) / 10 = 1. This means that the student scored 1 standard deviation above the mean.
What is the difference between a Z score and a standard deviation?
The Z score equation is relatively simple: Z = (X - μ) / σ, where X is the data point, μ is the mean, and σ is the standard deviation. This equation allows us to determine how many standard deviations an individual data point 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 from the mean the data point is.
Conclusion
How it Works
A standard deviation measures the amount of variation in a dataset, while a Z score measures how many standard deviations an individual data point is away from the mean.
