Find the median of 45, 76, 32, 58, 16, 27, 64 and 35.
Given:
The numbers are: 45, 76, 32, 58, 16, 27, 64, 35
Concept used:
The median is the middle value of the data when it is arranged in ascending order.
Solution:
Arrange them in ascending order:
16, 27, 32, 35, 45, 58, 64, 76
Since there are 8 numbers (even count),
the median is the average of the 4th and 5th numbers.
From the arranged list:
4th number = 35
5th number = 45
Thus, the correct answer is (B).
