Question 7 of light and matter, VCAA 2008.

They really should have accepted only one value for the determined value of Planck's constant, seeing as if you subbed in any two points from the set given, you would only get 5 x 10^-15.

Does anyone know why they accepted a range? Because how else would you work out the gradient anyway?

Because not everyone is able to draw perfectly accurate, perfectly straight lines :). Plus, without conclusive figures, calculating rise/run is entirely subjective. . .
