(10, 12, 12, 13, 13)
(10, 12, 12, 13, 13)
It is (8+6+11+12+13)/5 = 10
If you have a plot with 5 10 15 13 and 12 the mean is where you add them all up 5+10+15+13+12=55 then, you divide by how many numbers there are in the plot 5 10 15 13 12 so divide by 5 then you have 11. do you get it?
to work out a mean value you just add all the numbers and divide by how many there are. (6+8+10+11+12+13+13+34)/8=13.38
