Today, new my column is released, so I take a day off.

"Over the AI(11) ---- beyond a reach of our imagination of AI"

Artificial intelligence that accounts for the future - Measure tool of treasure created by mankind

-----

This time, I tried taking up "statistical processing" which is plain, not so popular.

"A guy who doen't knows the standard deviation, never talk about AI technology"

And I will never say that.

A status of writer is decided by number of readers. so I have to flatter the readers ...correction, I have to behave gentlemanly.

So, I just "think that".

-----

By the way, in this column, I wrote

"If your child's teacher who answers" standard deviation? What? ", I recommend you to tell it to the headmaster, and to ask to let him/her get fired"

So, to all the teachers who want to avoid dismissal, I will teach them how to calculate the standard deviation easily,

When there are 40 people in your class, you

(1)remember the score of the sixth from the top

(2)remember the score of the sixth from the bottom

(3) calculate ((1) - (2)) / 2

This (3) is about a value of standard deviation.

please run away, in the meantime.
