Body lengths of coyotes
Use the top slider to explain how jittering (random vertical displacement of crosses) helps to separate dense groups of crosses and therefore describes density better. The Redo jittering button changes the random displacement of crosses.
Mention that the least amount of jittering that separates the crosses is best — moving the slider about half-way for this data set.
The bottom slider changes the display into a stacked dot plot. The slider initially moves the crosses horizontally into classes, then moves them vertically into stacks.
Mention that stacked dot plots are usually better than jittered ones for data display.
The data set contains the body lengths (cm) of 83 coyotes that were captpured in Nova Scotia.
