The mean is the average of the numbers.
It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
For example: What is the Mean of these numbers?
6, 11, 7
<span><span>Add the numbers: 6 + 11 + 7 = 24
</span><span>Divide by how many numbers (there are 3 numbers): 24 / 3 = 8</span></span><span>The Mean is 8
Hope this helps :)</span>
Personally, i would identify if the data shows a straight line or has a curve near the end.
