The following table shows the weights of 12 students.

Answer :

Draw the table as below,



We have;


N = 15(0dd number)


Median = value of the term


= value of 8th term


= 53


Now,


∑fx = 796 and ∑f = N = 15


Mean =


Hence,


Mode = 3(median) – 2 (mean)


= 3×53 - 2×53.06


= 159 – 106.12


= 52.88


So, Mean, median and mode are 53, 53.06 and 52.88
