Mean Median Mode Calculator
Paste a dataset to calculate mean, median, mode, sum, range, minimum, maximum, and sorted values. Use a custom unit label so scores, measurements, or amounts stay clear.

Mean, median, and mode inputs
Paste a dataset to calculate center, frequency, range, and sorted order with odd, even, and decimal checks.
Supports up to 500 numeric values. Separate values with commas, spaces, semicolons, pipes, or line breaks.
Use any measurement label. The calculator keeps mean, median, percentile, and standard deviation in that unit; variance is squared.

Center and spread checks
| Measure | Value | Check |
|---|---|---|
| Sum | 25 points | All numeric values added before dividing for the mean. |
| Mean | 5 points | Sum divided by the number of values. |
| Median | 4 points | Middle value after sorting, or the average of two middle values. |
| Mode | 4 points | Most frequent value. If every value appears once, there is no repeated mode. |
| Minimum / maximum | 2 points / 9 points | Smallest and largest values in sorted order. |

Calculate center and frequency from one dataset
Arithmetic mean
Add all values and divide by the number of values to find the average.
Median from sorted order
Use the middle value for odd counts or average the two middle values for even counts.
Mode and range
Find the most frequent value and compare the smallest and largest values.
Mean, median, and mode formulas used on this page
Center statistics describe a dataset from different angles. The mean uses every value, the median uses sorted position, and the mode uses frequency.
Working formulas
Mean
mean = sum of values / n
The arithmetic average uses every value in the dataset.
Median
middle sorted value, or average of two middle values
The median depends on sorted position, not the original input order.
Range
range = maximum - minimum
Range gives a quick spread check but is sensitive to extreme values.
Symbols
- n - count
- The number of numeric values detected in the dataset.
- sum - total
- All numeric values added together before calculating the mean.
Center statistics with visible sorted-value checks
Dataset checks before answers
- Values can be pasted with commas, spaces, semicolons, pipes, or line breaks.
- Sorted-order previews make median, percentile, minimum, maximum, and range checks easier to audit.
- Odd-count, even-count, and decimal presets expose the edge cases that often cause manual mistakes.
- A custom unit label keeps scores, dollars, kilograms, centimeters, seconds, or dimensionless values clear.
Method labels on every result
- Sample and population standard deviation are separated because they use different denominators.
- Percentiles show both nearest-rank and interpolated methods instead of hiding the convention.
- Z-scores are marked unitless while the raw value, mean, and standard deviation retain the dataset unit.
- Copy and print controls help move checked results into worksheets, reports, and study notes.
Mean, median, and mode support for learning and review
Students
Check homework datasets while seeing sorted values, formulas, and the method behind each output.
Teachers
Build classroom examples for center, spread, percentile, z-score, and sample-versus-population lessons.
Analysts
Quickly validate small datasets before moving values into spreadsheets, notebooks, or reports.
How it works in three quick steps.
Paste the dataset
Enter numbers separated by commas, spaces, semicolons, pipes, or line breaks.
Check sorted order
Review the sorted values so median and mode results can be verified.
Read the center values
Use mean, median, mode, sum, range, minimum, and maximum for the final summary.
Save or print descriptive statistics
Copy result summary
Copy the dataset count, main statistic, and method notes into assignments or analysis notes.
Print a checked worksheet
Print inputs, result cards, formula tables, FAQs, and related tools for offline review.
Verify sorted order
Use the sorted preview to confirm the exact values used for median and percentile positions.
About this mean median mode calculator
Toolarithm's Mean Median Mode Calculator is designed for quick descriptive statistics without hiding the dataset checks. The calculator starts with the pasted values, parses common separators, shows the values it detected, sorts them, and then calculates the mean, median, mode, sum, range, minimum, and maximum. The result card keeps the main center values above the fold, while the table below explains how each statistic can be verified.
The page is useful for classroom statistics, small research examples, score checks, measurements, and spreadsheet verification. Mean, median, and mode often answer different questions about the same dataset, especially when values are skewed or repeated. Because the calculator includes odd-count, even-count, and decimal presets, users can test common edge cases before trusting a pasted dataset from another source.
