Question

A data arranged in descending order has 25 observations. Which observation represents the median ?

A) 15^th

B) 14^th

C) 13^th

D) 12^th

Answer 1

Correct option is: C) 13^th

n = Total number of observations = 25

\(\therefore\) \(\frac {n+1}2\) = \(\frac {25+1}2 = 13\)

Hence, if data having 25 observations arranged in ascending order then 13^th \(((\frac {n+1}2)^{th})\)observation represents the median of the data.

Answer 2

Correct option is: C) 13^th
