may sing to the tune of ABBA's "Dancing Queen"
If you have skew,
then you must choose to use median and IQR ooh
Symmetry, standard deviation and mean
If you have skew,
then you must choose to use median and IQR ooh
Symmetry, standard deviation and mean

may sing to the tune of "BINGO"
When the data that you have goes through a transformation
Addition and subtract, addition and subtract
Addition and subtract
Affects the center only
When the data that you have goes through a transformation
Multiply and divide, multiply and divide, multiply and divide
Affects them both

Give me a second now
I need to get my words straight
I need to learn the vocab that is all about the data’s shape
Uniformed, symmetrical, skewed to the right and the left
Will there be an outlier or is the shape regular
I know I then choose the center, though…
Do I pick mean or median?
So that I don’t get confused the spread that I choose to use is IQR or standard deviation
When the AP test approaches and I want to get a 5, I know what to do:
Describe the distribution
Shape and outliers
Center and spread
Describe the distribution
Shape and outliers
Center and spread
When the AP test approaches and I want to get a 5, this song will help me to thrive
