Problem: Harmonic mean {{10-20,20-30,30-40,40-50,50-60},{5,18,42,27,8}} [ Calculator, Method and examples ]

Solution:
Your problem -> Harmonic mean {{10-20,20-30,30-40,40-50,50-60},{5,18,42,27,8}}

Harmonic mean :
 Class Mid value (x)(2) f f/x 10 - 20 15 5 0.3333 20 - 30 25 18 0.72 30 - 40 35 42 1.2 40 - 50 45 27 0.6 50 - 60 55 8 0.1455 --- --- --- --- -- -- n=100 sum (f/x)=2.9988

HM of X = n/(sum (f/x))

=(100)/(2.9988)

=33.3468
