Frequently asked questions
What if every number appears once?
Then there is no mode — the calculator reports exactly that instead of pretending. Mode is the only average that is allowed to be absent, unlike the mean and median, which always exist for numeric lists.
Can a dataset have two modes?
Yes — a bimodal list like 2, 2, 5, 9, 9 has both 2 and 9 tied at two appearances, and the calculator returns both. Ties are common in real data, so returning both is the honest answer.
Is the mode affected by outliers?
Barely — one extreme value appearing once cannot hijack the mode the way it drags the mean. A salary list of 30k through 60k with one 5 million still has its everyday mode near the small values.
