Answer» Correct Answer - Option 2 : \({1\over2}[{n\over2}^{th} term \space + {({n\over2} + 1})^{th} term]\) Formula used: If the total number of observation given is odd, then the formula to calculate the median is: Median = {(n+1)/2}th term If the total number of observation is even, then the median formula is: Median = [(n/2)th term + {(n/2)+1}th term]/2 where n is the number of observations Note:- In the official question option 1 is marked as correct but correct answer is option 2 |
