[grey_whiskers #331] Your trolling is now failing. (Pats head.)

(Hears sound of knock on wood.) Who's there? Oh, you again.

Your senile act is long past the state of failing. It has failed, utterly.

[grey_whiskers #327] You're foaming at the mouth, child.

Respect your elder, son.

[grey_whiskers #327] I gave a real-world example in which it made a difference whether you a single maximum value, or not.

Yes, you gave an example at your #314:

I know what the mode is.
Let's say you have three people. You, the guy next door, and Bill Gates.
The average is going to be far more than your net worth or the guy next door.
If you have an outlier, then, and the average is far far less than the outlier, then the count of people having less than the mean, *must be* far more than those over the mean.

It was a useless example which demonstrated that you did not know what you wre talking about, as I more than adequately documented.

At #318 I gave sample data where the result was

Mean value 9.96
Mode value 11.00
Median value 10.00

proving your *must be* claim was nonsense.

Moreover at #321 I quoted Math is Fun to demonstrate that you were full of crap:

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".

Strictly speaking, in your chosen multimodal example, you would have three modes, just as I stated. Your example had three modes and was trimodal or multimodal.

And I quoted Math is Fun to document why your chosen example, with only three discrete values, was useless to discuss mode:

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

You made up an example where mode is not useful. It was not easy to make up an example where mode is not useful, but you were up to the task.
