Dear student

Observations in ascending order are as follows : 14, 19, 23, 38, 40, x - 2, x + 2, 62, 68, 74, 85, 93 Number of observation = n = 12 (even number) Median = \frac{{(\frac{n}{2})}^{th} observation + {(\frac{n}{2} + 1)}^{th} observation}{2} \Rightarrow 53 = \frac{{(\frac{12}{2})}^{th} observation + {(\frac{12}{2} + 1)}^{th} observation}{2} \Rightarrow 53 = \frac{6^{th} observation + 7^{th} observation}{2} \Rightarrow 53 = \frac{x - 2 + x + 2}{2} \Rightarrow 106 = 2 x \Rightarrow x = 53
