Fruitfly Data
Description
This data gives fecundity for female fruitflies, Drosophila melanogaster.
The fecundity is the number of eggs laid, per day, for the fruitfly's first
14 days of life. There are three strains: A control group, NS, Nonselected
Strain, as well as RS, a strain bred for resistance to DDT and SS, a strain
bred for susceptibility to DDT. Each strain contains 25 measurements. It is
of interest to compare the level of fecundity across strains.
Format
A data frame with 75 observations on 2 variables.
[,1] fecundity numeric Number of eggs laid, per day, per
fruitfly
[,2] strain factor Strain of fruitfly (NS, RS,
SS)
