See the spread

The same five values, read by four cards at once: max, min, avg, med. One list of numbers, more than one honest summary.

You can change the numbers right here, but changes made here are not saved. To keep what you build, use “Open in CalcAnyway” and edit there.

Try moving it

Change the 9 in x₂ to 90 — max and avg jump, med barely moves. Robustness to outliers, made visible.
Make all five equal — the four cards agree. No spread, one summary.
