First, reorder the numbers so they go from least to greatest. It should look like this:
-11, -9, -6, 0, 2, 18, x, 20, 36, 37, 46, 47, 51.
Mean: 19.25
The mean is the average. To find it, add all numbers together and divide by how many numbers there are.
Median: 19
The median is the center number in the ordered line of numbers. I added a bolded variable (x), so you can see where it is. Because it's between two numbers, add those numbers and divide by 2.
Mode: N/A
There's not a mode. A mode is a repeating number in the sequence.
Range: 62
Range is the difference between the largest and smallest number.
47.)
The range is larger than the highest temperature because the temperature values are both positive and negative. Due to this, the smallest number (-11) becomes positive as the negative sign is distributed to it and adds to the largest number (51).
48.)
Again, mean is the average. Add all values together and divide by the number of values there are.
