Volume of algae as function of increasing concentrations of a herbicide
Description
Dataset from an experiment exploring the effect of increasing concentrations of a herbicide on
the volume of the treated algae.
Usage
data(algae)
Format
A data frame with 14 observations on the following 2 variables.
conca numeric vector of concentrations.
vola numeric vector of response values, that is relative change in volume.
Details
This datasets requires a cubic root transformation in order to stabilise the variance.
