Variation

Variation
Lyric © 2022 Lawrence M. Lesser
may be sung to the tune of "Vacation" by the Go-Go's

Can’t seem to get my mind off of mu
But I think more is needed to view
What made it so clear
Temperatures here
Are either near 
40 or 100. 
 
[CHORUS:]
Variation in the distribution
Variation – how the data lays
Location’s not enough alone
Variation – it is all around us
Variation links to chance of things
Variation – something we need to know
 
With a shift of values, what’s undone?
SD and IQR won’t run!
But a change of scale
Will make them both sail
But not percentiles
Or a z-score (Repeat Chorus)
