Introduction

In this lab we’ll be looking at a dataset on measurements taken on 722 bycatch White-chinned Petrel Procellaria aequinoctialis caught predominantly by bottom longliners, tuna longliners, squid trawlers and general fish trawlers between 2000 and 2003.

We’ll be doing some exploratory data analysis and then some statistical inference.
