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

Mode, range, median? thats some :-D

I edited it five times and still got it wrong. I had it all laid out nice and it didn't format correctly.

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

To calculate the mean add the numbers together and divide the total by the amount of numbers:

Mean= sum of numbers ÷ amount of numbersIf you place a set of numbers in order, the

mediannumber is the middle one.If there are two middle numbers, the median is the mean of those two numbers.

The

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

The

rangeis 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.

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.
