The Correct Option is D
Solution and Explanation
Concept:
The median of a grouped distribution lies in the median class. Since the central class is $10-15$, the median is taken as the midpoint of this class interval.
Step 1: Identify the median class. The middle class interval is: $$ 10-15 $$
Step 2: Find its midpoint. $$ \text{Median} = \frac{10+15}{2} = \frac{25}{2} = 12.5 $$ Therefore, $$ \boxed{12.5} $$
Step 1: Identify the median class. The middle class interval is: $$ 10-15 $$
Step 2: Find its midpoint. $$ \text{Median} = \frac{10+15}{2} = \frac{25}{2} = 12.5 $$ Therefore, $$ \boxed{12.5} $$
