You can easily find the mean of a group of numbers by getting the average. You can do that by simply adding up all of the numbers and then dividing that number by the number of numbers that you have.

Add up the numbers, and then divide by the number of numbers in the set. This will give you the mean.
Only if you were asked to find the mean to the nearest tenth. If so, don't round each number; calculate the mean first and then round it to the nearest tenth.
Divide that number by 5 or Multiply it by 0.2
You find the mean of negative numbers the same way you find the mean of any numbers. You add them up and then you divide by the number of numbers. An example, using -3, -4, -6, and -9. The sum is -22. N is 4. The mean is -5.5.
You can't find the mode of a single number...but you can find the mode of a group of numbers The mode is the value with the highest frequency...that is, the value which appears the most often
