About These Measures

Mean, Median, and Mode

These are the three most common ways to describe the "center" of a dataset, and they can tell very different stories — especially when your data has outliers or is skewed.

What Each One Tells You

Mean — the arithmetic average. Sensitive to outliers, since one extreme value can pull it up or down.
Median — the middle value when sorted. Much more resistant to outliers than the mean.
Mode — the most frequently occurring value. Useful for categorical or repeated data.
Range — the gap between the smallest and largest value, a quick sense of total spread.

Worked Example

Quiz scores: 6, 7, 7, 8, 8, 8, 9, 10, 10, 15.

Mean = 8.8, Median = 8, Mode = 8, Range = 9
The mean (8.8) is higher than the median (8) — a sign the single high score of 15 is pulling the average up.
The median is often the more representative "typical" score here, since it isn't distorted by that one outlier.
