Answer: 0.75°C
Explanation:
You must first line up the temperatures from least to greatest.
-4.5, -4, -3.5, -2, -1, 0, 1.5, 2, 2.5, 4, 5.5, 6
To find the median in an even set of numbers, you find the average of the middle two numbers.
The middle two numbers in this set are 0 and 1.5.
To find the average of these two numbers, add them together then divide by two.
(0 + 1.5) / 2 = 0.75
The median temperature is 0.75°C.
Hope this helps!
