Question

Median of 2, 3, 4, 5, 6, 7 is ……………

A) 2 

B) 5.5 

C) 5 

D) 4.5

Answer 1

Correct option is: D) 4.5

Total No of observations is n = 6.

\(\therefore\) \(\frac n2 = \frac 62 = 3^{rd}\) and \(\frac n2 +1 \) = 3 + 1 = 4th

\(\therefore\) Median = \(\frac {3^{rd} \,observation + 4th \, observation}{2}\) = \(\frac {4+5}2 = \frac92 = 4.5\) 

Hence, the median of 2, 3, 4, 5, 6, 7 is 4.5.

Answer 2

Correct option is: D) 4.5
