      • Failing to consider the potential impact of outliers on results
        • You may also like
      • The statistical formula for outliers is only applicable to large data sets.

        • At its core, the statistical formula for outliers helps identify data points that significantly deviate from the norm. This is done by calculating the z-score, which measures how many standard deviations an observation is away from the mean. A higher z-score indicates a greater deviation, making it a potential outlier. The formula is based on the Gaussian distribution, which assumes that data points follow a normal distribution. By applying the formula, users can detect anomalies and trends in their data, gaining valuable insights into their operations.

      • Policymakers and government officials
      • Outliers are always bad or incorrect data points.

        • The z-score formula is used to calculate how many standard deviations an observation is away from the mean. The formula is: z = (X - μ) / σ, where X is the value of the observation, μ is the mean, and σ is the standard deviation.

    • Over-reliance on statistical methods

      • Can outliers be removed or excluded from the data set?
