Median Absolute Deviation Calculator

Paste your numbers. Calculate median absolute deviation and optional scaled MAD. Review the method and copy or download your results.

Enter a grid, paste values, or choose CSV, TSV, JSON, JSON Lines, XLSX, text or a statistics project. XLSX requires a worksheet choice and imports values only. Review headers and column mapping before calculating. The workspace supports up to 2 MB, 20,000 rows and 100,000 cells.

Import settings

Column mapping is available after opening the data. JSON object keys become column names. Grid column names are separate from its data rows.

  1. Paste your numbers
  2. Check your values and calculation settings.
  3. Calculate, review the method, and save your results.

How it works

Calculate median absolute deviation and optional scaled MAD from your own values. Use the fictional sample to try the calculation. Find the median of the absolute distances from the median. The optional multiplier 1.4826 gives a normal-consistent scale estimate.
