Frequently Asked Questions
Mean vs median?
Mean averages all values (outlier-sensitive); median takes the middle (robust). Billionaire-in-room datasets need medians.
What is mode?
Most frequent value(s) — sizes, votes, categories. Datasets can be bimodal; the tool lists all modes.
Skew detection?
Mean far above median signals right skew (a few huge values). Report both, never mean alone.
Do datasets upload?
No — statistics compute locally in your browser. Data never leaves your device.
Work mean, median and mode on one dataset?
For 2, 4, 4, 4, 5: mean is 19 ÷ 5 = 3.8, median (middle value) is 4, mode (most frequent) is 4. Same average family, three different stories.
