Potassium cyanate and trout eggs

Description

These data were collected in a toxocological experiment conducted at the University of Waterloo. Different concentrations of potassium cyanate were applied to vials of trout eggs. The eggs in half of the vials were allowed to water-harden before the toxicant was applied.

The variables are:

Concentr	toxicant concentration
Trouts	number of trout eggs
Dead	number of eggs which died
Insert	an indicator of whether the eggs were allowed to water-harden
