How it Works: A Beginner-Friendly Explanation
So, what are outliers, and how do you identify them? In statistical terms, an outlier is a data point that is significantly different from the rest of the data. Think of it as a peculiarity that doesn't fit the norm. To identify outliers, you can use a simple formula: Z-Score Formula = (X - μ) / σ, where X is the individual data point, μ is the mean, and σ is the standard deviation. By calculating the Z-Score, you can determine whether a data point is significantly different from the rest of the data.
