Question : Directions: The graph given below shows the daily income of 50 workers in a factory. Study the graph and answer the questions.
The median wages in the factory are:
Option 1: Rs. 140
Option 2: Rs. 138
Option 3: Rs. 150
Option 4: Rs. 160
Correct Answer: Rs. 140
Solution :
Here cumulative frequency = 50
25th term = 140
26th term = 140
So, median = average of 25th and 26th term = $\frac{140+140}{2}$ = 140
$\therefore$ Median wage = Rs. 140
Hence, the correct answer is Rs. 140.
