Correct Answer  Option 1 : 3
Concept:
Median of 'n' observations is the value at the central position when the data is arranged in ascending or descending order.
 For, odd n, median is the value at the \(\rm \left(\frac{n+1}{2}\right)\) position.
 For even n, median is the mean of values at \(\rm \left(\frac{n}{2}\right)\) and \(\rm \left(\frac{n}{2}+1\right)\) position.
Calculation:
Writing the cumulative frequencies, we get

198 
Since n = 198 is even, the median will be the mean of the values at \(\rm \left(\frac{198}{2}\right)\) = 99^{th} position and 99 + 1 = 100^{th} position.
From the above table, both the 99^{th} and 100^{th} values are 3.
Therefore, the median of the above data is 3.
