Calculate mean, median, mode, and range from any set of numbers instantly.
Enter numbers separated by commas.
While "average" commonly means the arithmetic mean, our calculator provides four statistical measures: mean, median, mode, and range. Each tells you something different about your data.
The middle value when numbers are sorted. For even counts, it's the average of the two middle values.
The most frequently occurring value. A dataset can have multiple modes or no mode.
Example: Numbers: 10, 20, 20, 30, 40
Mean = (10+20+20+30+40) ÷ 5 = 24
Median = 20 (middle value)
Mode = 20 (appears twice)
Range = 40 - 10 = 30
Mean is typically used for grade averages. However, if one score is unusually low/high, median might better represent your typical performance.
Mean includes every value in the calculation. One extreme value shifts the mean toward it, while median stays at the center regardless of outliers.
