Ice cream rates for a Vanilla brick for 12 months of a year are given :
January - Rs.190 , February - Rs.210 , March - Rs.250 , April - Rs.200 , May - Rs.225 , June - Rs.265 ,
July - Rs.270 , August - Rs.240 , September - Rs.217, October - Rs.203 , November - Rs.180, December - Rs.170
Find the Median of the rates.
For finding Median we first need to arrange the values in ascending order.
We get : 170 , 180 , 190 , 200 , 203 , 210 , 217 , 225 , 240 , 250 , 265 , 270
Number of observations (n) = 12
Median = (n2)th term + (n2+1)thterm2
= 6thterm + 7thterm2
= 210 + 2172
