may sing to the tune of Journey's "Faithfully"
How do I know what measure to use
Sometimes there’s symmetry
Sometimes there’s skew
When there’s skew, when there’s outliers
All I know is that I need resistance
The measure of center that is resistant to the skew
The measure of spread that is resistant too
Are the measures that I should choose to use
I guess that I should choose then
Interquartile range and median.
Symmetry, symmetry
Standard deviation and mean
Symmetry, Symmetry
Standard deviation and mean
