Solution and Explanation:
Approach Solution 1:
The problem statement informs that:
Given:
- The temperatures recorded at 6 in the morning in various parts of a specific country were 10, 5, -2, -1, -5, and 15 degrees Celsius
Find Out:
- the median of these temperatures
In order to find the median of a group of numbers, we need to arrange the numbers in such a way that the lowest comes first and the greatest comes last.
That means we need to arrange the temperatures in ascending order: -5, -2, -1, 5, 10, 15
Since the amount of numbers present in this group of temperatures is 6 i.e even, then the median will be equal to the average of two middle numbers.
Therefore, we can infer that the Median of these temperatures = (sum of -1 and 5) divided by 2 = (-1+5)/2= 4/2 =2
Thus the median of these given temperatures is 2
Correct Answer: (C)
