CenterLab
The three classic measures of centre — together.
Mean is the arithmetic average, median is the middle value when sorted, and mode is the most frequent value — they usually sit close together, but diverge sharply when outliers or skew are present.
Household income is a classic case: a few extremely high earners pull the mean well above the median, which is why 'median income' is usually the more representative figure for a typical household.

Mean: 5.7
Mean 5.7, median 5.5, mode 3 — a wide gap between mean and median usually signals skew from outliers.
