Mean-
Is also known as the average in a set of data.
Example:
In your set of data, you have the numbers 1,2,3,5,6 and 7.
You add up all the digits:
1+2+3+5+6+7=24.
Then you subtract 24 by the highest number in your set of data:
24-7=37
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
Average area
The Average function. For example, to get the mean of the cells from A2 to A15, you would use it this way: =AVERAGE(A2:A15)
In Maths, the mean is the mean average; in other words, the average. To calculate the mean (average), you add the numbers you have together and then divide that total by the amount of numbers of had..
You don't need to. Average deviation (about the mean) is always zero!
mean median and mode
The word "mean" means average. The mean temperature is the average temperature. To calculate it you add all the temperatures together and divide by the number of temperatures you added.
Total takings/number of guest = mean average
mean
It isn't clear what you mean by the "height of a velocity".
The mean is simply the average. Mean = Sum of data divided by the total number of observations.
The mean is a type of average. You have told us that the average age is 24. If this is the mean average then you have answered your own question. So first you need to establish whether the average you are quoting is the mean, median or mode average. If it is the mean average then you have your answer. If it is not the mean average then you can calculate this by summing all the ages and then dividing by the number of people whose ages you have just summed.
