#### 050-Song PARAdy: "I Graph The Line"

 PARA SINGS 16ax2 + bx + c  presents...."I Graph The Line"  (*aka "I Walk The Line", Johnny Cash)--------Official recording: YouTube HereLive video: YouTube HereKaraoke with Cash audio: YouTube HereKaraoke without audio: YouTube Here***Our correlation, we'll follow with care.If no outlier, balance all points there.We may go through points; if not, don't despair.Now, that sounds fine.I graph the line.(Median-Median)Three sections equal in their size at the outset.Then medians, for x and y we'll get.With slope defined, a nudge would be no sweat.Now, that sounds fine.I graph the line.(Least Squares)Perhaps a mean fit point will help us cope.Residuals we find, then squares we hope.Their areas get small, as we find slope.Now, that sounds fine.I graph the line.With any line drawn, finding 'r' won't change.And it's the same, should x and y exchange.That coefficient comes from how points are arranged.Now, that sounds fine.So graph the line.(Do your best!)Our correlation, we'll follow with care.If no outlier, balance all points there.We may go through points; if not, don't despair.Now, that sounds fine.I graph the line.

 PARA SINGS 15ax2 + bx + c  presents...."Only When We Train"  (*aka "Only When It Rains",     Astrid S & Frank Walker)--------Official video: YouTube HereFrank's channel static version: YouTube HereNot really karaoke version: YouTube Here***Why did I memorize that bad math rule?Exponents won't distribute, chart's our tool.Negative root when squaring goes out, that's cool.Understand meaning, that's where I'm leaning.New number systems mean perspectives change.New course means shift our meaning of a "range".Doing work daily means this all seems less strange.Practice makes better, be a go-getter.Since we can grow,Our skills will get better when we train.By cramming, you can't knowEnough, we need context in our brains.So it's only when we train, that we know.Yes, it's only when we train. That we grow.Yes, it's only when we train. That we know.Yes, it's only when we train. That we grow.Yes, it's only when we--Someone else may learn at a different speed,Our backgrounds and course choices count, indeed.Find out your pace by making the time you need,Don't think of testing, more personal besting.Since we can grow,Our skills will get better when we train.By cramming, you can't knowEnough, we need context in our brains.So it's only when we train, that we know.Yes, it's only when we train. That we grow.Yes, it's only when we train. That we know.Yes, it's only when we train. That we grow.'Cause it's only when we train, that we know.Yes, it's only when we train. That we grow.Yes, it's only when we train. That we know.Yes, it's only when we train. That we grow.Yes you, will grow,Your skills will get better as you train.By cramming, we can't knowEnough, you need context in your brain.And that's only once you've trained.
