NOTE: I will send the data file to your email since the website doesn’t accept the type of file
The data in the file rabbit.dat are the eosinophil counts taken from blood samples of 40 healthy rabbits. This can be read into R with:
scan(‘rabbit.dat’)
Instead of measuring variation by the standard deviation we consider the coefficient of variation (cv) which is the sample standard deviation divided by the sample mean. The cv does not depend on the units of measurement and measures variation relative to the size of a typical value.
