Find the mean and median of weight of 10students which are as under 39,57,33,47,32,34,48,39,40,39 .



Dear Student,

Weight of students: 39, 57, 33, 47, 32, 34, 48, 39, 40, 39Number of students = 10Mean = Sum of observationsNumber of observationsMean of weights = 39+57+33+47+32+34+48+39+40+3910 = 40810=40.8For finding the median, we first need to arrange the observations in ascending order:32, 33, 34, 39, 39, 39, 40, 47, 48, 57Median (in the case of even number of observations) = (n2)thobservation+(n2+1)thobservation2 =(102)thobservation+(102+1)thobservation2  = 5th observation + 6th observation2 = 39+392 = 782 = 39
