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.

• A. 217
• B. 210
• C. 213.5
• D. 220.5

Answer 1

The correct option is C

213.5

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 = $\frac{(\frac{n}{2}{)}^{th}term+(\frac{n}{2}+1{)}^{th}term}{2}$

= $\frac{6thterm+7thterm}{2}$

= $\frac{210+217}{2}$

= Rs.213.5
