    While outliers can affect the mean, it's not always the case. If the data is normally distributed, the mean is generally a reliable measure of central tendency.

    x̄ = (Σx) / n

    For example, let's say we have the following data set: 2, 4, 6, 8, 10. To calculate the mean, we would add up the values (2 + 4 + 6 + 8 + 10 = 30) and then divide by the number of values (5). The result would be a mean of 6.

      How it Works

      The mean is always affected by outliers.
