add the data and divide by the number recorded temperatures:
mean (-5-3-1+3) /5 = -6/

????????

Example:
What is the Mean of these numbers?
6, 11, 7

Add the numbers: 6 + 11 + 7 = 24

Divide by how many numbers (ie we added 3 numbers): 24 ÷ 3 = 8

The Mean is 8

Mean is the average, so add all together (-6) and divide by the number of days (5) which gives you -1.2

Are the mode, range and median not the, well, how do I put this? The mode, range and median? Not the mean? :thinking:

The mean is the most common measure of average.
To calculate the mean add the numbers together and divide the total by the amount of numbers:
Mean = sum of numbers ÷ amount of numbers

If you place a set of numbers in order, the median number is the middle one.
If there are two middle numbers, the median is the mean of those two numbers.

The mode is the value that occurs most often.
The mode is the only average that can have more than one value.

The range is the difference between the highest and lowest values in a set of numbers.
To find it, subtract the lowest number in the distribution from the highest.

Easiest way if you are ever stuck is use Excel.

Just type each number into a column, then highlight them all and down the bottom right it shows you the average, the total and any other crap you want to know.
