Question

find the median of the weights (in kg) of eight persons: 47, 60, 82, 49, 58, 80, 59, 63.

Answer 1

Hello dear,

Median = No. of obs/ total no. of obs
Median =  47+60+82+49+58+59+63/8
Median =  54.875

Answer 2

Arranging in ascending order :
47, 49, 58,59, 60, 63, 80, 82
Since number of observations is even, the median is given by finding the average or mean of the two middle most observations :
So, median = (59+60)/2 =119/2 = 59.5
