Question

The blood LDL (in mg/dl) present in the samples of 11 patients are: 5, 19, 42, 11, 50, 30, 21, 0, 52, 36, 27. Find the median?

Answer 1

Solution:

 

Arranging the given blood LDL levels in increasing order:

0, 5, 11, 19, 21, 27, 30, 36, 42, 50, 52.

 

n = 11 i.e. odd; so the median will be:

(n+1)/2 th term

⇒ (11+1)/2 ^th term

      ⇒ 6^th term = 27

 

 Thus, the median blood LDL level in the patients' is 27 mg/dl. 

 

The median blood LDL level in the patients' is 27 mg/dl.
