    Z-scores help identify outliers and anomalies in a dataset, allowing you to make more accurate predictions and decisions.

    Z-scores, also known as standard scores, measure how many standard deviations an element is from the mean. In simple terms, a Z-score indicates how far a value is from the average value in a dataset. To calculate a Z-score, you need to know the mean and standard deviation of the dataset. The formula for calculating a Z-score is: Z = (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation.
