Given:
The numbers are: 13, 15, 12, 21, 10, 14, 12.
Definition of Median:
The median is the middle value of a data set when it is arranged in ascending order. If the total number of values is odd, the median is the middle value.
Solution:
1. Arrange the numbers in ascending order:
10, 12, 12, 13, 14, 15, 21.
2. Count the number of values:
Total values = 7 (odd).
3. Identify the middle value:
The middle value is at position
The 4th value is 13.
Final Answer:
(B) 13
