Here modal class is 201 - 202, since it has a maximum frequency which is 26.l= 201 , f1= 26, f0= 12, f2=20, h= 1
Mode= l + (f1-f0/2f1-f0-f2) ×h
Mode= 201 +(26-12/2×26-12-20)× 1
Mode= 201 + (14/52 - 32)× 1
Mode= 201 + (14 /20 )× 1
Mode= 201 + (14/20)× 1
Mode = 201 + 0.7
Mode = 201.7 mg
Hence, the modal weight is 201.7 mg.
