Answer :

GIVEN:


FORMULA USED:


Mean =


Median =


Mode = Maximum number of terms


Let weight of student be x


And number of student be frequency (f)



For Mean:


Mean =


∑xf = 188 + 150 + 371 + 112 + 240


= 1061


∑f = 4 + 3 + 7 + 2 + 4


= 20


Mean = = 53.05


For Median


Total frequency (N) = ∑f = 20


N/2 = = 10


Which lies in commutative frequency 14


Which is having value of x to be 53


Median = 53


For Mode


Maximum number of terms(f) in above table is 7


7 terms are of value 53


Mode = 53
