Mean (Average) is calculated by adding all values and dividing by the total number of values. It can be distorted by outliers, as seen in the example provided.
Median represents the middle value when data is sorted and is not affected by outliers.
Mode is the most frequently occurring value in a dataset.
Understanding when to use mean, median, or mode depends on the nature of the data: use mean for clean data, median for data with outliers, and mode for identifying the most frequent value.
