The average of the numbers. Add them all up then devide by the amount of numbers in the data

the mean is basically just another for for the average. what you do is you add up all the numbers, and then divide the sum by the number of variables..
like if you did a survey where you asked 10 people how tall they were. let's just say that 4 people were 65 inches, 3 people were 61 inches, and 3 people were 68 inches. when you add up all the numbers, the total would be 647.. then you divide that number by the number of people, which is 10. so 647/10 would be 64.7, which means that the mean of the set of data is 64.7 inches.
hope i helped :)

HEy,
The mean is the average of a group of answers you have.
If, for example you had questioned 5 people on how good on a scale of 1 to 10 Pepsi cola tasted and they voted as follows....6 7 9 9 4 then you would add them all together and then divide by 5 because that is how many people (answers/options) you had then the mean would be 7
All the numbers you have collated up and divide them up by how many numbers/responses you had.

Basically you add all of the numbers together and divide by however many sets of numbers there are. Example: the mean of 4 and 2 is 3 because I added 4 and 2 and then divided by 2.

a mean is like an average so all you do is add all the numbers and divide by the number of numbers you added
ex. 1
2
3
4
4
