Question
The marks in a subject for 12 students are as follows:
31, 37, 35, 38, 42, 23, 17, 18, 35, 25, 35, 29
For the given data, find the median
Solution
Given data is 31, 37, 35, 38, 42, 23, 17, 18, 35, 25, 35, 29.
Rearranging the given data in ascending order,
17, 18, 23, 25, 29, 31, 35, 35, 35, 37, 38, 42
Here, n = 12 .....(Even)
Median = `("Value of" (n/2)"th observation" + "Value of" (n/2 + 1)"th observation")/2`
= `("Value of" 6"th observation" + "Value of" 7"th observation")/2`
= `(31 + 35)/2`
= `66/2`
= 33
