実例

Example: With Dataset (comma-separated) = 4, 8, 15, 16, 23, 42, the Range & Midrange Calculator gives Range: 38, Midrange: 23.

よくある質問

Is range affected by outliers?

Yes, heavily — since it only uses the two extreme values, a single outlier can dramatically change the range.

Is midrange the same as the median?

No, midrange averages only the min and max, while the median is the middle value of the sorted data — they usually differ.

What inputs does the Range & Midrange Calculator need?

You'll need to provide: Dataset (comma-separated). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Range & Midrange Calculator?

The Range & Midrange Calculator applies the formula exactly as calculated — Range = maximum value − minimum value. Midrange = (maximum + minimum) / 2. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Range & Midrange Calculator free to use?

Yes, the Range & Midrange Calculator is completely free, requires no signup, and runs instantly in your browser.
