The median of the data : 78,56,22,34,45,54,39,68,54,84 is

(a) 45
(b) 49.5
(c) 53.5
(d) 54

Solution:

Arranging the data in ascending order, we have

22, 34, 39, 45, 54, 54, 56, 68, 78, 84

Here, the number of observations n = 10, which is even

∴ Median of the data

= Value of 102th observation+Value of 102+1th observation2

= Value of 5th observation+Value of 6th observation2

= 54+542

= 1082

= 54

Thus, the median of the given data is 54.

Hence, the correct answer is option (d).
