INSTRUCTIONS

You should interactively change the bin width by clicking on and then dragging the arrow underneath the bin width scale.

1. Try large bin widths, then try small ones.

2. Which bin width (large or small) do you think provides the best picture of the underlying data?

What is your interpretation of the "best" histogram? That is, what accounts for it's pattern of variation?

And always give credit where credit is due:
