Question

A boy scored the following marks in various class tests during a term, each test being marked out of 20.
15, 17, 16, 7, 10, 12, 14, 16, 19, 12, 16
What is his median marks?

Answer 1

Arranging the given marks in ascending order,
7, 10, 12, 12, 14, 15, 16, 16, 16, 17, 19
Here N = 11

∴ Median is `(("N" + 1)/2)^"th"`term

= `((11 + 1)/2)`
= 6^th term
∴ Median marks = 15.
