After rewriting all sets of data from smaller to greater, I found that the last series is the one that is represented by the plot box:
79,86,88,88,92,98,100,106,115,136
Why? Because The median is 95 (like the box)
because the outliers are > 115 (up to 136)
because their is no outlier on the left by the mini value of 79
Y=x+4
x=0 y=4
x=1 y=5
x=2 y=6
x=3 y=7
plot the points at
(0,4) (1,5) (2,6) and (3,7)
