Example

*Data.Semigroup.Means> getAM . foldr1 (<>) . map am $ [4, 36, 45, 50, 75]
42.0
*Data.Semigroup.Means> getGM . foldr1 (<>) . map gm $ [4, 36, 45, 50, 75]
30.000000000000007
*Data.Semigroup.Means> getHM . foldr1 (<>) . map hm $ [4, 36, 45, 50, 75]
15.0
*Data.Semigroup.Means> :m + Data.Ratio
*Data.Semigroup.Means Data.Ratio> getMM . foldr1 (<>) . map mm $ [4, 36, 45, 50, 75] :: Ratio Int
79 % 2
*Data.Semigroup.Means Data.Ratio> getAM . foldr1 (<>) . map am $ [4, 36, 45, 50, 75] :: Ratio Int
42 % 1
