Potassium cyanate and trout eggs


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
