Survival of Rats After Radiation Doses
Description
The ‘survival’ data frame has 14 rows and 2 columns.
The data measured the survival percentages of batches of rats who
were given varying doses of radiation. At each of 6 doses there
were two or three replications of the experiment.
Usage
data(survival)
Format
A data frame with 14 observations on the following 2 variables.
- dose
The dose of radiation administered (rads).
- surv
The survival rate of the batches expressed as a percentage.
