# Fitting the Line

may sing to the tune of "Draggin' the Line" (Tommy James and Bob King)

(Back-up vocals in parentheses)
Plotting the data, on X and Y,
Finding the slope, with most points nearby,
We want to find the angle, of the trend's incline,
Fitting the line (fitting the line),

Upward slopes make r positive,
Slopes trending down, make it negative,
From minus-one to plus-one, r can feel fine,
Fitting the line (fitting the line),
Fitting the line (fitting the line),

Points align, how will the data shine?
If you have upward slopes, it'll give you a plus sign,
Fitting the line (fitting the line),
Fitting the line (fitting the line),

How strongly will your variables relate?
Is there a trend, or just a zero flat state?
You want to know what your analysis will find,
Fitting the line (fitting the line),
Fitting the line (fitting the line),

Points align, how will the data shine?
Your r will be minus, if the slope declines,
Fitting the line (fitting the line),
Fitting the line (fitting the line),

(Guitar solo)

Points align, how will the data shine?
If you have upward slopes, it'll give you a plus sign,
Fitting the line (fitting the line),
Fitting the line (fitting the line)...
