Enter a set of numbers to calculate mean, median, mode, range, count and sum and see the values in sorted order.
Averages, standard deviation, z-scores, normal distributions and probability calculations.
Enter numbers separated by commas or spaces. The calculator returns mean, median, mode, range, count and sum and also shows the sorted values used to find the median.
For 2, 4, 4, 7, 8, the sum is 25, mean is 5, median is 4, mode is 4 and range is 6.
Continue with the probability calculator, standard deviation guide, or z-score guide.
For 2, 4, 4, 7, 18, the mean is (2 + 4 + 4 + 7 + 18) ÷ 5 = 7. The median (middle value) is 4 and the mode (most frequent value) is also 4. The range is 18 − 2 = 16.
Why the answers differ: 18 raises the average but does not change the middle number. A set can have no repeated mode or more than one mode; interpret the distribution rather than relying on one statistic.
Yes. If multiple values tie for the highest frequency, the calculator lists all of them.
The result reports no repeated mode.
