VCAA 2010 E1 q3 core

How did they get the standard dev to be close to two.

I would have picked two by just looking at the graph, but there must be some logic to it right?

do you look at the box plot and just estimate from the Q1 and Q3?

no, you dont look at the boxplot instead your look at the other graph ( i dont even know the name of it) i think it's called a histogram from question 1 and refer to Hodgeyhodgey's link i think his explanation is suffiecient :)
