Math Calculators
Average Calculator
Calculate the mean, median, mode, range, sum, and count of any list of numbers.
Quick guide
Paste or type a list of numbers separated by commas or spaces. The calculator returns the mean, median, mode, range, sum, and count, which together describe the center and spread of your data.
Read the full explanationHow It Works
The mean sums all values and divides by the count; the median is the middle value; the mode is the most frequent. Together they describe a data set’s center and spread.
Formula Used
Mean = (x₁ + x₂ + … + xₙ) ÷ n; median = middle of sorted values; range = max − min.
Example Calculation
For 4, 8, 15, 16, 23, 42: mean = 18, median = 15.5, range = 38, sum = 108.
Practical Use Cases
- Average grades, scores, or expenses.
- Compare mean vs. median for skewed data.
- Summarize any quick list of numbers.
