12 + 7 + 13 + 10 + 3 = 45/5 = 9
(10, 12, 12, 13, 13)
(10, 12, 12, 13, 13)
To find the mean of the numbers 3, -10, -2, 13, and 12, add them together: ( 3 + (-10) + (-2) + 13 + 12 = 16 ). Then, divide the sum by the number of values, which is 5: ( 16 / 5 = 3.2 ). Therefore, the mean is 3.2.
Average is a casual word . You need to know the MEAN Mean = {10+12+14+16)/4 mean = 52/4 mean = 13 The answer!!!!
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?
It is (8+6+11+12+13)/5 = 10
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
7, 10, 11, 12, 13, 14, 17
Mean = 14 Median = 12 Mode = 12
mean = 19 median = 12 mode = 12
Mean: 20.2222222 Median: 12 Mode: 11 Range: 79
