Strictly parse a finite number series and report arithmetic mean, median, repeated mode, minimum, maximum, range, sum, and exact count.
A quick decision brief for this specific tool
One complete series of up to 1,000 finite numbers separated by commas, semicolons or whitespace
Arithmetic mean, median, repeated mode if present, minimum, maximum, range, sum and exact parsed count
Rejects the entire series when any token is invalid, then summarizes every retained value without automatic trimming or outlier removal
Choose your path
Strictly parse one entered finite-number series and report arithmetic mean, median, repeated mode, minimum, maximum, range, sum and count without silently discarding data.
Distinguish arithmetic mean, median and mode from one another.
Enter the complete series, verify count and sum, then compare the three center measures.
Can reproduce the arithmetic mean and understands a series may have no repeated mode.
Know immediately when a malformed token would change the count.
Paste comma-, semicolon- or whitespace-separated finite values and resolve every named invalid token.
The tool rejects the whole malformed series instead of silently dropping a value.
Avoid assuming the arithmetic mean is automatically representative.
Compare mean, median, repeated mode and range, then inspect distribution, units, sampling and missingness externally.
Does not receive automatic outlier removal or a recommendation for the “best” center.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.
Tools you might need next
Calculate population or sample standard deviation, variance, quartiles, IQR fences, z-scores, and descriptive distribution statistics from a strict number list.
Calculate mean, median, and genuinely repeated modes from one strictly parsed finite list, with count, extrema, and sorted audit output.
Calculate percentages in seven modes with visible formulas, strict input validation, signed percentage change, and symmetric percentage difference.
Commas, semicolons and whitespace separate values. Empty input, non-finite values, malformed tokens and more than 1,000 numbers return an explicit error instead of a partial result.
The arithmetic mean uses the sum and exact count. The median sorts the series and selects the middle value, or averages the two middle values for an even count.
Arithmetic mean = Σ entered values ÷ countA mode is listed only when the highest frequency is repeated. Mean, median and mode describe different aspects of center; range gives only maximum minus minimum.

A student checks the complete set 10, 20, 20, 30, 40 and verifies sum, count and center measures.
→ Mean 24; median 20; mode 20; sum 120; count 5
An analyst checks four finite values and confirms the median is the mean of the two sorted middle values.
→ Median 2; count 4
A reviewer pastes 10, 20, N/A, 40 and receives an invalid-token error instead of a misleading three-value average.
Compare mean with median, repeated mode, range and distribution shape; extreme values can move the mean substantially.
Resolve every invalid token and document missingness. Dropping values changes count, sum and all derived measures.
Paste up to 1,000 finite values separated by commas, semicolons, or spaces; any invalid token rejects the complete series so the count remains auditable.
