Standard Deviation of the Slope

Lyrics © Mary McLellan
may sing to the tune of Adele's "Hello"

Slope.Varies.
It’s the standard deviation of the slope
You need to know

Slope.Varies.
It’s the standard deviation of the slope
You need to know

If you sample many times
I’d expect the slope you find
Of the relation between X and Y
To vary this much
On average over time.

If you sample many times
I’d expect the slope you find
Of the relation between X and Y
To vary this much
On average over time.
