# The following table shows the weights of 20 students.Calculate the mean, median and mode.

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

CONCLUSION: The data is having Mean to be 53.05

Mode to be 53

Median to be 53
