1.

If total number of observations are even, then the median of these observations is equal to ______.1. \({1\over4}[{n\over4}^{th} term \space + {({n\over4} + 1})^{th} term]\)2. \({1\over2}[{n\over2}^{th} term \space + {({n\over2} + 1})^{th} term]\)3. \({3\over2}[{n\over2}^{th} term \space + {({n\over2} + 1})^{th} term]\)4. \({1\over2}[{n\over2}^{th} term \space + {({n\over3} + 1})^{th} term]\)

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
