The length and breadth (in millimetres) of two samples of jellyfish from Hawkesbury River in NSW, Australia.
One sample is from Dangar Island, the other from Salamander Bay.
Variables:
Breadth
The breadth in mm
Length
The length in mm
Site
The site: 1 is Dangar Island; 2 is Salamander Bay
Data Quality:
There are no missing values.
Source:
Hand et al., dataset 335,
from a book by Lunn and McNeil.
Notes:
A regression analysis of length against breadth
(or vice versa) using Site as a covariate indicates that the
same regression line can be used for both sites.
But beware!
Plot the data first, and things are more interesting.
