💡 Examples

Test scores: 85, 90, 78, 92, 88

Mean = 86.6 | Median = 88 | Range = 14

Dataset: 2, 4, 4, 4, 5, 5, 7, 9

Mean = 5 | Median = 4.5 | Mode = 4

❓ FAQ

The mean is the arithmetic average (sum divided by count). The median is the middle value when numbers are sorted. The mode is the most frequently occurring value. Each measures central tendency differently and is useful in different contexts.
Use the median when your data has outliers or is skewed. For example, household incomes — a few extremely high values pull the mean up, but the median better represents the typical value.
