Mean, Median & Mode Calculator
Calculate the mean (average), median (middle value), mode (most frequent value), and range of any data set.
The statistical measure is 6.4444.
With 9 values, the sum is 58. The mean (average) is 6.4444. Sorting the values reveals a median of 7. The most frequent value(s) is 7. The spread from minimum (2) to maximum (13) gives a range of 11.
How to Use the Mean, Median & Mode Calculator
Calculate mean, median, mode, and range for any data set using our free statistics calculator. Enter your values as a comma-separated list to get a complete descriptive statistics summary. The tool displays step-by-step calculation working so you can verify each result.

Mean vs. Median vs. Mode: Comparing Central Tendencies
Learn the three measures of central tendency, when to use each, and why using mean for skewed data leads to misleading conclusions.

Mean is the arithmetic average — sum all values, divide by count. Median is the middle value when data is sorted in order. Mode is the most frequently occurring value. The mean is sensitive to outliers; the median is resistant to them. When a dataset is skewed, the median is often more representative of a 'typical' value.
Can a dataset have no mode?
Yes. If every value appears exactly once, there is no mode. Some datasets are multimodal — they have two (bimodal) or more values that appear with the highest equal frequency.
When should I use median instead of mean?
Use the median when your data is skewed or contains outliers. For example, household income data is heavily skewed by extremely high earners. The median household income is a better measure of what a 'typical' household earns than the mean, which is pulled upward by billionaires.
