Find out the median of the following frequency distribution:
|
13 14 15 17 |
14 |
The correct answer is Option (2) → 14 Step-by-Step Explanation for Finding the Median: The frequency distribution has N = 55 observations (total frequency). Since N is odd, the median is the value of the $\frac{N+1}{2}$th observation in the ordered list. $\frac{N+1}{2} = \frac{56}{2} = 28$th observation. Now, construct the cumulative frequency (cf) table:
The 28th observation falls where cf first reaches or exceeds 28.
Thus, the median is 14. |
