Is there any advantage to standard deviation as opposed to mean deviation (usually termed "mean average deviation")?
Standard deviation just seems like a really roundabout (and slightly off) way of getting at what people actually want to know, which is the average deviation from the average.
Which can be found with (|x_1-x| +|x_2-x| + ... + |x_n -x|)/n, where x is the mean. I mean, am I huffing paint here? Am I the only one seeing this, or is this a meme like using pi rather than tau that's just hung around?
The octopus man thinks it's because retards (journalist) misinterpreted Karl Pearson's term for what had been called root mean square error, but what the fuck was he doing playing around with root mean squares and their errors? What's the point of those?
