It is to remove the negative deviations that would tend to cause an average to be around 0. Squaring, doing a mean on that square, then taking a square root gives a measure where you get a kind of average deviation from the middle *regardless of direction* of that deviation.
been there done that back when I was in electronics, Thanks for the memories. Had a First-class FCC license with a radar endorsement if anyone knows what that was back in the Day.
I've learnt so much watching you video - exactly what i was looking for- Thanks very much
Excellent
Thank you!
It really makes a lot of sense but it confuse me when the y value is squared.
