Of course I am. And that means that when I quoted Math Is Fun at #321, they must have been wrong also. Please explain how Math Is Fun got it wrong.

More Than One Mode

We can have more than one mode.
Example: {1, 3, 3, 3, 4, 4, 6, 6, 6, 9}

3 appears three times, as does 6.

So there are two modes: at 3 and 6

Having two modes is called "bimodal".

Having more than two modes is called "multimodal".

And,

Grouping

In some cases (such as when all values appear the same number of times) the mode is not useful.

Math Is Fun appears correct to me, and your chosen example with its three different values appears useless for a discussion of mode.
