Question
Find the median of following data set.
12, 6, 87, 9, 54, 23, 43, 19, 56, 34, 69, 74
12, 6, 87, 9, 54, 23, 43, 19, 56, 34, 69, 74
Answer: Option A
:
A
When you arrange the datain ascending order, you get:
6 9 12 19 23 34 43 54 56 69 74 87
If number of observations is odd then median is the(n2)th term
Ifit is even then median is the mean of the (n2)th and(n2)+1) th term.
Here the numberof observations is 12 - even,
Therefore, the median will be an average of 6thand 7thobservation.
So, Median=34+432=772=38.5.
