Standard dataset
For 2,3,3,5,7: count=5, sum=20, mean=4, median=3, mode=3, and range=5.
Calculate mean, median, mode, range, sum, minimum, maximum, frequencies, and sorted values for up to 10,000 numbers.
Mean, median, and mode describe the center of a dataset in different ways. The mean uses every value, the median uses the sorted middle, and the mode identifies the most frequent value or values.
No single measure is best for every dataset. Outliers can strongly affect the mean while the median is often more resistant.
Add every value and divide by the number of values.
mean = sum of values / countThe method depends on whether the count is odd or even.
middle sorted value, or average of two middle valuesRange describes the full spread between extremes.
range = maximum − minimumFor 2,3,3,5,7: count=5, sum=20, mean=4, median=3, mode=3, and range=5.
For 1,2,3,4: mean and median are 2.5, every value appears once, and there is no mode.
For 1,1,2,2,3, both 1 and 2 are modes.
A very large or small outlier changes the mean because every value contributes to it.
The median can better represent a typical value when data are skewed.
Frequency counting uses exact parsed numeric values. Similar-looking decimals such as 1.1 and 1.1000001 remain distinct. When every distinct value has the same frequency, the result is “No mode.”
Separate values with commas, spaces, tabs, or new lines. The calculator accepts finite positive, negative, decimal, and zero values, with a maximum of 10,000 entries.
The mean is the sum divided by the number of values.
The median is the middle sorted value, or the average of the two middle values for an even count.
The mode is the most frequently occurring value.
Yes. Every value tied for the highest frequency is reported.
Yes. This calculator reports no mode when all distinct values occur equally often.
The range is the maximum minus the minimum.
Yes. Negative numbers, zero, integers, and decimals are valid.
Yes. Outliers can move the mean substantially, while the median is usually less affected.
