How to use the mean, median and mode calculator
Compute the mean, median, mode and range of a data set. Enter data values in the field above; the count, mean, median, mode, range are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “mean median mode calculator”, “median and mode calculator”, “find the mean calculator”, “average of numbers”, “central tendency”.
Formula
Variables
- d — Data values
Worked example
With data values = 4,8,6,5,3,2,8,9,2,5, the calculator gives count ≈ 10; mean ≈ 5.2; median ≈ 5; mode ≈ 8; range ≈ 7.
Tips for accurate results
- Separate the values with commas; the order does not matter because the calculator sorts them.
- For an even number of values, the median is the average of the two middle values.
- Check whether the data have a meaningful mode; a set with no repeated values has none.
Common mistakes
- Including outliers in the mean without checking whether they are errors.
- Reporting the mode for continuous measurements where repeated values are unlikely.
- Mixing data from different groups or units in one list.
Frequently asked questions
What is the mean, median and mode calculator used for?
Compute the mean, median, mode and range of a data set. It helps with questions such as “mean median mode calculator”, “median and mode calculator”, “find the mean calculator”.
What is the formula for the mean, median and mode calculation?
Count = len(d). Mean = mean(d). Median = med(d). Mode = mode(d). Range = hi(d)-lo(d). Here d is data values.
What inputs do I need for the mean, median and mode calculator?
You need data values. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the mean, median and mode calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the mean, median and mode result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
